Professional Development Program

Program Dates : 23rd to 25th January 2014. Venue : Hotel Radha Regent, Chennai.

By Dr. Richard Lundstrom

This seminar will present an introduction to Vehicle Dynamics from a

vehicle system perspective. The theory and applications are associated with

the interaction and performance balance between the powertrain, brakes,

steering, suspensions and wheel and tire vehicle subsystems. The role that

vehicle dynamics can and should play in effective automotive chassis

development and the information and technology flow from vehicle system

to subsystem to piece-part is integrated into the presentation. Governing

equations of motion are developed and solved for both steady and

transient conditions. Manual and computer techniques for analysis and

evaluation are presented. Vehicle system dynamic performance in the

areas of drive-off, braking, directional control and rollover is emphasized.

The dynamics of the powertrain, brakes, steering, suspension and wheel

and tire subsystems and their interactions are examined along with the

important role of structure and structural parameters related to vehicle

dynamics. Physical experiments, applicable to vehicle dynamics are also

introduced.

Learning Objectives

By attending this seminar, you will be able to:

Summarize how vehicle dynamics is related to the voice of the

customer

Identify important vehicle system parameters useful for effective

application of vehicle dynamics to chassis development

List and explain parameters that effect vehicle performance relative to

drive-off, braking, directional control and rollover

Identify physical measurements needed to effectively apply vehicle

dynamics to passenger cars and light trucks

Define the value of vehicle dynamics simulation in the development

and evaluation of vehicles

Explain the balance required between ride, directional control and

rollover and the essential process for this balance to be obtained for

marketplace vehicles

Who Should Attend

product design, testing, quality, process or development will

benefit from attending.

Prerequisites
