- Manufacturing suspension systems is not a new or upcoming process, it has been in the market for years but still, the survival of the fittest plays a key role for the respective manufacturer. So, the main objective of the vehicle suspension system is to improve ride comfort, road handling and vehicle stability. A suspension system plays a vital role in a smooth and safe riding experience. So, an analysis of the suspension system should be done, and the results should be in the standard range. In this paper, the simulations of a quarter and half car passive spring and air suspension were analysed for ride comfort and suspension travel by mathematical modelling of the quarter-and-half car with the help of a system of equations. As these mathematical equations cannot be solved directly, these equations are solved with the help of library blocks of MATLAB/ Simulink software by giving different road profiles as single bumps, step functions and irregular road profiles as excitations for the suspension system. The results obtained after simulations of quarter-and-half car passive spring and air suspension were compared in order to get to the end which suspension system is better performing in comparison to ride comfort and suspension travel concerning the road profile that is given as input to the MATLAB/Simulink software.
