As vehicle technology becomes advanced, the vehicle ride quality is improved. Safety of automotive suspension system is influenced directly with quality ride of passenger. This study aims at the improvement of automotive shock absorbers. Static and vibration analyses are analyzed at car cushion buffer with spring force due to the weight movement of vehicle. The maximum equivalent stresses and strains are calculated and six different natural frequencies are applied with each mode of vibration. Maximum deformation vibration value is also derived by the condition of harmonic vibration. As the durability of advanced automotive shock absorber can be improved by applying this study result with the design of car cushion buffer. ride quality gets better and the damage can be prevented.
