### Abstract

Suspensions ystems have always been animportant part of consideration in automobile considering the ride comfort and passenger safety. A modern vehicle utilizes advanced suspension systems and therefore various studies regarding quarter car suspension analysis have been done. The present workon quarter car model passing over a Gaussian bump is carried out to investigate the effect of spring stiffness on the ride comfort considering a speed range of 10 km/hr –20 km/hr. The equations of the quarter car system are solved by MATLAB and the behavior of the system with different spring stiffness is analyzed with respect to its effect on sprung mass displacement and Root Mean Square (RMS) value of the sprung mass displacement
