Motion Simulation and Force Analysis in Built Car Dynamic Model

Modern car engineering relies more heavily on mathematical models and computer simulations than on experiments. A digitally designed car can let any of the parts be tested, amended, or replaced without any of the costs of actually making them. Because of this general trend, engineers are expected to receive solid training in mathematical modeling of complex physical systems and learn how to solve the resulting equations on a computer. In this paper, we use python to build two different cars (BMW and Chevrolet Cavalier) in linear and non-linear force models to observe how their motion and force change in given turn profiles. The study aims to model the car by python and find out how it turns. First, we develop a simple model of a car. Then we use python to define two kinds of cars (BMW and Chevrolet Cavalier), two kinds of turn profiles (U-turn and lane change) and two forces models (linear and nonlinear). Finally, we use the parameters we define and some physical equations to find the force and solve the car's motion.
