Mass Properties and Automotive Lateral Dynamics

A special one day (eight hour) seminar is being presented by the Texas Chapter of the Society of Allied Weight Engineers on September 23rd at the Dallas-Fort Worth Airport Hotel. Unlike other courses that titillate, but leave the participant no more capable after the course than before, this course is quantitative not merely qualitative. The course learning objectives include enabling the student to be able to make reasonably accurate estimates via basic calculations/simple computer simulation of Rollover SSF (Static Stability Factor), Roll Gain, Lateral Steady-State Maximum Acceleration (Skidpad), and the associate Steer Angles/Slip Angles/Body Side Slip Angle at that steady-state condition.

Also, this course will enable the student to make an estimate of Lateral Transient Acceleration (Slalom) characteristics such as the Dynamic Index in Yaw (DIY), Transient Yaw Center, and the Ackermann Yaw Rate. Lastly, this course will enable the student to make estimates of Directional Stability (Oversteer/Understeer) Characteristics such as the Understeer Coefficient, Static Margin, Steady State Steering Angle, Characteristic Velocity (Understeer), Critical Speed (Oversteer), and the handling transition Critical Speed (Oversteer).

Individuals interested in taking the course, and automotive venders wishing to exhibit their products and/or services at the regional conference, are directed to the SAWE Texas Chapter website. All individuals completing the course will receive a Certificate of Completion, a copy of the Course Vu-Graphs (MS-PowerPoint), a copy of SAWE Paper #3528 (“Mass Properties and Maximum Lateral Acceleration”), and a Max Lateral Acceleration Estimation Spreadsheet (MS-Excel).
