摘要：Safety and driving comfort for car’s driver are both dependent on vehicle’s suspension system. Safetyrefers to the vehicle’s handling and braking capabilities whereas comfort of the occupants of a car correlates totiredness and ability to travel long distance with minimal annoyance. The need for dampers arises due to the roll andpitches associated with vehicle maneuvering, and from the roughness of roads. Rapidly increasing power availablefrom the internal combustion engine made higher speeds routine; plus the technical aptitude of the vehicle andcomponent designs, coupled with a general commercial mood favoring development provided an environment that ledto invention and development of shock absorbers. FSAE is an international design competition that aims at building aprototype of a Formula style race car for the non-professional weekend autocross racer. Each team designs, builds andtests a prototype based on a series of rules whose purpose is both to ensure onsite event operations and promote cleverproblem solving. One of the major cause of failure of the suspension system is the failure of shock absorber spring dueto fatigue. Taking this into account, our aim is to select an appropriate material which can be used for the shockabsorber spring by analyzing certain commonly used materials. This report follows a detailed design methodology anddescribes the criteria and factors for selection of the materials. It encompasses several iterations, and establishesreasoning for the most suitable material. The designed shock absorber is a mono-tube hydraulic type. Hence based onthe shock absorber used in the race car our project aims at optimizing the material of the shock absorbers. Designing ofthe model was done on solidworks and analysis was performed on ansys. This study explains the groundwork laid forthe selection of the best shock absorber material which can be used in the years to come.
