Suspension system is one of the most crucial components of any automobile. The present years have seen a drastic change in the design of a typical suspension system, mainly taking into account the critical aspects such as rider comfort and vehicle handling. A good suspension system should be able to provide a compromise between both of rider comfort and road holding. The spring design plays a major role in determining the optimum level of suspension performance. This paper focuses on the study of the effect that is caused on the values of those attributes that determine the rider comfort and road holding, by changing the spring design framework. A spring is taken and re-modeled by changing minor geometrical attributes and simulated on a 2 DOF passive suspension system modeled on MATLAB-SIMULINK to obtain time graphs to assess the ride comfort and road holding. The present work deals with inducing geometric non-linearity in the spring by changing its geometry and to study its direct effects on the suspension parameters.
