Using simulation to learn about vehicle dynamics

Mathematical models of vehicles are used to learn about vehicle behaviour. Traditionally, computer simulation analyses have been limited to experts who have specific questions about the vehicle dynamic performance. However, less experienced engineers can also run mathematical models when simulation technology is combined with a modern graphical interface and a database of vehicle properties. This paper shows how engineers and others can use simulation to rapidly gain experience in vehicle dynamics. Fundamental concepts involving steer, braking, and throttle inputs are demonstrated in an easy-to-use simulation environment. The paper describes features in the user interface that support quick learning on the part of the user. It also lists model features that serve to emphasise the most significant vehicle properties.
