Dynamic Analysis of Half-Car Suspension Systems Using MATLAB Simulink and ANSYS

This study presents the dynamic modelling, simulation and analysis of a half-car suspension system using both passive and active suspension configurations. A vertical half-car 4-DOF (degree of freedom) model is developed to analyse pitch and bounce motions. The project integrates MATLAB Simulink for time-domain analytical simulations and ANSYS finite element analysis (FEA) for numerical validation. The objective is to evaluate suspension behaviour under road disturbances at speeds ranging from 10 to 45 km/h. The analysis demonstrates that active suspensions significantly improve ride comfort and handling compared to passive systems, although they involve higher complexity and cost.
