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
Automotive engineers and quality professionals who work in
product design, testing, quality, process or development will
benefit from attending.
Prerequisites
Participants should have an undergraduate engineering degree
and some exposure to vehicle dynamics.
Topical Outline
DAY ONE
The Role of Vehicle Dynamics in Passenger Car and Light Truck
Product Development
Vehicle Dynamics and the Voice of the Customer

drive-off, braking, ride and handling
o Thinking systemically about automotive chassis design
and development through the logic of vehicle dynamics
Effective Metrics for Vehicle Dynamics
o Vehicle system, subsystem and piece-part metrics used to
link vehicle dynamics to vehicle system design and
development: bounce frequencies, lateral acceleration
gain, understeer gradient, roll gradient, roll stiffness, etc.
