Standards and Practices – A Call to Action

SAWE Blog - Tue, 2019-06-11 18:51

At the kickoff of Standards and Practices Day at the 2019 International conference in Virginia, I talked about donuts.

An internationally known chain of donut shops noticed their sales dropping. To find out why, they asked their customers if there was a problem with the donuts. The answer was no – the donuts were as good as ever. But sales kept dropping. Then the donut shop asked a different question: what do the customers think of their donut shop experience? The response surprised them: the donuts were great, but the coffee was bad. That’s something the owners had not considered: get better coffee, sell more donuts. And it was only learned because the donut shop asked an open-ended question, allowing the customers to communicate what was important to them.

SAWE Recommended Practices (RPs) are a vital resource available to a wide range of customers. Mass Properties Engineers refer to them. Companies and government agencies require their use. But there are significant gaps in what our RPs cover. As the new Vice President of Standards and Practices, my role is to shepherd the development of new RPs and the revision of existing ones to ensure they stay relevant to our customers.

But what to do first?

At the International conference I asked all of the Industry Committees to emulate the donut shop and  ask their customers what is important to them. Understanding their customer priorities will allow the Industry Committees to know which RPs to focus on and will motivate them to complete their tasks on time.

My call to action is this:

By the end of 2019, each Industry Committee should document their customers’ needs, the Committee’s priorities, and the time-based plans to create Recommended Practices which support their customers’ needs.

This does not mean that all current work should stop. A small number of RPs, such as those being converted to ANSI standards, have been identified by the SAWE  executive as high priorities and should continue to be worked. I have asked the Industry Committees to review and update the development schedule for each of these to ensure they will be published on time to meet the customer needs.

Developing and updating Recommended Practices is a vital part of ensuring the SAWE remains a professional society relevant to our industry needs. The Industry Committees need volunteers to help with this important work. If you wish to help out, please contact me at standards@sawe.org.

SAWE International Conference and the coming year

SAWE Blog - Fri, 2019-05-24 13:49

The SAWE International Conference just held by the Hampton Roads chapter was very nice and informative. Thanks to all (Corporate Partners and Company Members, host committee, individual participants, etc…) involved in making it happen.

I enjoyed both the Aerospace and Marine sessions as it allowed me to maximize my technical intake having to choose between many topics of interest. It would be nice if the SAWE can continue to offer multiple tracks at these conferences. That means individuals writing papers. Start forming your ideas now as I’d wager the content at this conference spurred many to the thinking “how can I use this experience to write about an experience of my own”.

I also enjoyed getting reacquainted with my fellow SAWE-ers in person. Whether being invited to a meal, chatting about life / work / SAWE in the hospitality suite, or enjoying one of the outings together like the dinner cruise, there are always smiling faces there to greet you, and even wish you well on your journey forward once the conference is done. As new Executive Director Bill Boze states, face to face interactions provide lasting memories.

Best Wishes as we approach our American holiday Memorial Day. I’m going to take the time to recharge, spend time with family, and maybe even grill an award winning hamburger. Afterwards, I will get back to the business of SAWE.

My Executive Vice President membership and projects team will be in touch with your chapters. We need to kick off the remainder of the year focusing our efforts on the goals of building up your chapters through membership and project support. This will support goals of your region as well as goals of the society laid out by new President John Hargrave.

I look forward to a prosperous 2019-2020 SAWE year.

Sincerely,

Clint Stephenson, SAWE Executive Vice President

Wednesday Conference Highlights

SAWE Blog - Wed, 2019-05-22 16:21

The day started with an open forum on weight control. The forum was very interactive with a lot of great points across the industries. Conversation included how we, mass property engineers, see things differently and we need speak up on mass properties, how smaller companies or subcontractors may need the support to ensure they are going in the right direction, remembering that smaller companies likely don’t have a mass properties engineer, incentives vs. penalties, cost of a pound or the value of a pound, and tying weight to performance. Lot of other great points and conversations occurred. These forums are great for everyone to see all the different point of views across the industries and across companies big and small.

Dan Otlowski of Space Electronics started off Aerospace Session 1 with a presentation on measuring weight and CG of manned spacecraft. Damian Yanez presented to the group the Welcome to SAWE presentation he has worked on. The presentation goes into detail the benefits to SAWE for both new members and potential corporate sponsors. This is open for members to use and chapters — great way to try and reel in new members! Amanda Cutright, NASA Langley Research Center, finished out the morning with a presentation on the Ascent Abort 2 for the Orion spacecraft. We do not want have crew members launched without the ability to abort. AA-2 is the next flight test in the exploration systems development program.

The afternoon Aerospace Session started with Dudley Cate, NAVAIR (retired) provided a presentation on weight and design data for WWII era aircraft. I am personally looking forward to being able to read this paper! Larry DiSano, Ensinger, finished the session with a presentation on Thermoplastic Composites for small parts.

We can’t say it enough, thank you to all our vendors who presented throughout the week!

Monday Conference Highlights

SAWE Blog - Mon, 2019-05-20 16:30

We started off the conference with opening speaker, Dawn Schaible, Director of Engineering at NASA Langley Research Center. She provided insight to NASA Langley’s past, present, and future. She overviewed NASA’s planned return America to the moon in 2024. This will include America’s first woman to step foot on the moon.

Anne Weiss and Rosemary Smith followed up with a rousing and eye opening presentation on how learning is changing for children. We need to reimagine learning and we need to inspire the future STEM students

The Statistics Session 1 had great presentations by Doug Fisher, Manuela Bucci, and David Hansch. Manuela was presented with honorary mention for her paper with Colin MacFarlane.

Bill Boze, John Hargrave, and Yi-Ling Tam presented after lunch on the Mass Properties Certification SAWE is working towards. They reviewed the benefits for SAWE and its members, market survey results that have helped build their roadmap, and a notional model. If you want to be involved in the certification process, please contact Yi-Ling

Anjie Emmett started off the afternoon statistics session. Having worked on the abort system for the Orion space crew module, she discussed applying the law of propagation of uncertainties. Robert Hundl followed with an overview of evaluating Center of Gravity Envelope using a probabilistic approach. He went over Monte Carlo Simulations in Excel and how we can use these for sensitivity studies as well as providing us with a sense of risk.

I ended the day with Nick Marickovich’s presentation on his journey on the Appalachian Trail and how backpack weight effected this. Great presentation!

I would love to hear how the other sessions went and your thoughts on the day and the presentations!

SAWE Conference Update – Standards and Practice Day changes

SAWE Blog - Wed, 2019-04-17 09:24

We have changed the format of SnP Day on Tuesday of the SAWE Conference in Norfolk VA.  We will only have a 30 minute opening an no recap session at the end of the day.  This will give each industry committee more time for discussions and some other exciting activities. The industry committee meetings will be from 8:30 to 5:00PM with the traditional coffee breaks and SnP Luncheon from 12:00 to 1:30 PM.

I am pleased to announce the following additional activities:

RP C- 9 Data Exchange – ISO-10303-242 Meeting from 3:30-5:00 in room 1783

Sebastian-Verian Herda will lead a meeting to define the scope of their project titled Mass Properties Digital Data Attributes for PLM data exchange & Reporting,  The purpose of the meeting is to review and to agree on a Project Proposal.   As I understand it (Andy Schuster VP-SnP), the purpose of the project  is create cconsistent PLM data and exchange protocols will simplify MPD functionality set up in PLM & ERP systems. The STEP AP 242 file (ISO 10303-242) is a system independent file format and is the best established specification within the Automotive, Aerospace, and Defence industries. It specifies the application protocol for Model based 3D engineering.  The STEP effort will be added to the other data exchange methods used by SAWE members such as MPEX, and RP M-1 to create a Cross Industry Function Recommended Practice.  The meeting will clarify my interpretation.

Mass Properties Engineer Certification Discussions

Each Industry Committee has set aside an hour of the day to discuss the impact of this program to their industry.  The program will be presented in a 90 minute presentation on Monday afternoon during the technical session.  The program leaders Yi-ling Tam, John Hargrave, Bill Boze and Clint Stephenson, will visit each meeting to get feedback based on a set of open ended questions to draw out your opinions.  From discussions at the SnP Standards Review Board meeting, we know that the impact of the Mass Properties Engineer Certification program will be dramatically different between industries, and we want to know how dramatic.  For example the Marine and Military Aircraft industries may want everything in English, while the Offshore industry may want the training materials and exams in English, Portuguese and Korean so that the detailed design and construction workers can do things in their native language.  The committee would like your thoughts on the program.

Weight Engineers Handbook – Update Discussions

Damian Yanez, and Andy Schuster will visit each Industry Committee for a 30 minute discussion of what should be updated in the new revision of the handbook.  For example :

  • We know that some sections are so out of date (i.e. Crew Systems and Power Systems from the 1960’s Mercury program), and need to be updated.  The existing sections will not help us  to get to the moon in 2024 or mars in 2035. 
  • We will also  ask each IC to commit to reviewing sections in the handbook that apply to their industry, by the end of the summer.  All we want to know whether the 2011 edition has the right information..  For example we’ll ask the marine Industry Committee to review the Marine section of the Handbook for errors omissions, etc.
  • Finally, we will get commitments from those Industry Committees such as the offshore, for their schedule to provide a new section to the handbook.

The Gulfstream team of MPE’s is about a third of the way through converting the old handbook into MS Word.  This is a significant accomplishment!!!  We owe it to them to assure the data they convert or include is up to  date and accurate.

Automotive Lateral Dynamics and Mass Properties Course Available at the 78th Int. Conf.

SAWE Blog - Tue, 2019-03-12 15:40

Automotive Lateral Dynamics and Mass Properties
by Brian Paul Wiegand

On May 20th at the Norfolk Hilton (“The Main”) an eight-hour course in “Automotive Lateral Dynamics” will be offered under the auspices of the SAWE as part of the society’s 78th International Conference. The course objective will be to enable the attendees to make reasonably accurate maximum lateral acceleration, rollover lateral acceleration, directional stability, and steering responsiveness determinations in the course of vehicle design. In route to attaining that objective, attendees will also become acquainted with such things as the calculation of roll resistance, suspension roll center location, sprung mass roll axis inclination, sprung mass roll inertia, sprung mass roll moment arm, sprung mass roll angle under lateral acceleration, vehicle roll gain, vehicle dynamic index in yaw, transient center of rotation location, and transient yaw inertia. There will also be considerable time spent on “Ackermann Steering Geometry” relationships and the behavior of tires under lateral load.

The seminar achieves its objective through a classical engineering approach that emphasizes determining vehicle lateral performance through simple models and simulations which are easy to comprehend and apply. Mass properties will play a major role as attendees will become acquainted with the principles of “weight accounting,” mass properties manipulation, and mass properties optimization.

This seminar is very important for anyone engaged in vehicle design, in particular, those designing with an emphasis on performance, and special effort has been expended to make it particularly relevant for those involved in the SAE Student Formula Design Competition. However, no one completing this course will walk away without having acquired some degree of enlightenment; as well as a Certificate of Achievement, print-out of the course Vu-Graphs, electronic (flash drive) copies of the SAWE Paper #3528 (“Mass Properties & Maximum Lateral Acceleration”), and the seminar’s “Maximum Lateral Acceleration Estimation Spreadsheet” (MS-Excel).

Additional course information can be found at this link: SAWE Conference Announcement and Training Program .

The course is open to students and mass properties professionals alike; the cost of registration for full-time students is only $50! Individuals desirous of attending this seminar should inform their student motorsport team leaders, contact brnwgnd@aol.com, and/or register on the conference web site at http://www.sawe.org.

Your organization needs competent mass properties engineers

SAWE Blog - Fri, 2019-03-08 13:30

According to a survey conducted by the Society of Allied Weight Engineers in 2018, organizations that design, build and/or operate aeronautical, marine, offshore or land vehicles need to promote the value of mass properties engineers within their organization to ensure vehicles can operate to their intended performance and safety parameters.  Simultaneously, organizations must focus on replacing and transferring the knowledge and experience of mass properties engineers who will be leaving in large numbers in the next 5 to 10 years.

The aforementioned is the leading paragraph to a letter being distributed to the leaders in government and industry to promote the value of mass properties engineering, while also inviting them to learn more about SAWE and how SAWE can address the collective needs of those organizations who need competent mass properties engineers.  The attached letter and accompanying enclosure have been distributed to the leadership of over 200 addressees  worldwide.  We want to increase the reach of this letter by asking you to share it with your fellow mass properties engineers and elevate this letter up your management chain to garner support for increased organizational awareness and involvement.  We also encourage you to utilize this letter to secure financial support for attending the next SAWE International Conference in May in Norfolk, Virginia.

Regards,

Bill Boze

President, Society of Allied Weight Engineers

Mass Properties Engineer Certification Program

SAWE Blog - Fri, 2019-03-08 07:29

An email was sent to membership about a Mass Properties Engineer Certification. Below is the email you should have received along with a survey. This is an important opportunity for the Mass Properties career field, and we strongly encourage all members of SAWE to take the survey.

SAWE is exploring creating a Mass Properties Engineer Certification program.  The envisioned program would provide mass properties engineers with credentials of their qualifications in a tiered level of experience structure.  It would provide organizations with confidence that certified mass properties personnel have qualifications recognized by industry standards that will produce safe, efficient, and top quality results for their products.  Eventually we envision qualifiying this certification program for ANSI accreditation and ISO compliance. 

The following is a survey to get your feedback and thoughts about Mass Properties Engineer Certification.  The program is currently in development and results of our exploration will be reviewed this May at the International Conference both at the Board of Director’s Meeting and in a special forum on Monday afternoon.  Please take the survey and give us your thoughts and feedback.
