GROUND VEHICLE DYNAMICS
in a Distributed Interactive Simulation Environment
Sponsored by:
The Institute for Simulation and Training
University of Central Florida
COURSE OBJECTIVES:
The objectives of the Workshop are to provide students with the theoretical
background and practical examples of the dynamic modeling of land vehicles
for real-time simulation. Distributed Interactive Simulation issues are also
discussed. The fundamental theories of kinematics and dynamics will be
reviewed. Practical examples will be used to guide the students through the
procedure of dynamic modeling of both wheeled and tracked vehicles. Finally,
numerical methods in real-time simulation will be discussed.
WHO SHOULD ATTEND:
Project Engineers and technical staff of vehicle manufactures' research and
engineering laboratories, simulator manufactures' and simulator users who
need to do dynamic modeling in the jobs This course is especially oriented to
real-time ground vehicle simulation. A basic knowledge of dynamics is
desirable.
COURSE CONTENT AND SCOPE:
This course provides a comprehensive explanation on how to model a dynamic
system. The fundamentals of kinematics and dynamics are first reviewed.
Coordinate systems and the coordinate conversion techniques will be explained
in detail. The single rigid body equations of motion are derived and are
later expanded to multiple rigid body systems. The use of symbolic multibody
programs to generate equations for real-time solutions is covered. Modeling
approaches for multibody programs are then covered. Basic concepts in vehicle
dynamics, including modeling approaches for the suspension systems and tires
are described. Numerical methods that are used to solve the equations of
motion are studied with emphasis on real-time issues. The DIS related issues
such as coordinate conversion, dead reckoning, and the development of a new
vehicle systems using DIS
will be discussed.
