The five-degree-of-freedom vehicle model is widely used by suspension research institutions and scientific organizations for suspension optimization using various software tools. MATLAB has become increasingly prevalent and plays a crucial role in vehicle dynamics research. Vehicle vibration dynamics simulation and analysis extensively utilize MATLAB/Simulink modules, where researchers can implement mathematical models using differential equations, transfer functions, or state-space representations to simulate vertical, pitch, and roll motions.

Detailed Documentation

In today's world, the vehicle suspension system constitutes an extremely important component. Consequently, numerous suspension research institutions and scientific organizations continuously optimize the five-degree-of-freedom vehicle model. These entities utilize various software tools for research, including MATLAB, which has gained significant popularity recently. MATLAB plays a vital role in vehicle dynamics research, not only for suspension system optimization but also for vehicle vibration dynamics simulation and analysis. Through MATLAB's Control System Toolbox and Simulink environment, engineers can implement quarter-car or half-car models using state-space equations (e.g., ode45 solver for numerical integration) to analyze bounce, pitch, and roll dynamics. Therefore, an increasing number of researchers are learning and applying MATLAB to better study and optimize vehicle suspension systems, ultimately enhancing vehicle safety and comfort.
