Short Course # PD-2

Vehicle System Dynamics I- Road Loads, Acceleration and Braking

Custom designed in-depth instruction material for professional development and advancement of select Mechanical and Electrical Engineers. Participants must have had courses in Statics and Dynamics to benefit from this short course.

This short course helps the engineers acquire in-depth knowledge of the dynamic behavior of the vehicle as one total system with additional knowledge of major subsystems influencing vehicle dynamics. Instruction delivery is (5) half-day morning sessions.
