A suspension system or shield is a mechanical device designed to minimize or absorb shock impact and distribute kinetic energy. The purpose of the protection commitment is to absorb or disperse energy. Within a vehicle, it mitigates the impact of traversing rough terrain, resulting in enhanced ride quality and increased comfort due to significantly reduced effectiveness of disturbances. When a car is traveling on a flat road and the wheels encounter a bump, the spring is rapidly compressed.

The compressed spring will strive to revert to its original compressed length, thereby rebounding beyond its average height and lifting the person. At that point, the vehicle’s weight will compress the spring below its usual stacked height. Consequently, this causes the spring to rebound.

This pattern of weaving is repeated iteratively, with diminishing intensity each time, until the process of improvement ultimately ceases. If skipping is left unregulated, it will not only result in an unbalanced ride, but also make it difficult to handle the vehicle. The configuration of the spring in the suspension system is essential.

Aim of the project: Design and Analysis of Shock Absorber Spring By Using Cad/Cae Tools

                        In this project a shock absorber is designed and a 3D model is created using solid works. The model is also changed by changing the thickness of the spring. Structural analysis done on the shock absorber by different materials.

The analysis is done by considering loads, bike weight, single person and 2 persons. Structural analysis is done to validate the strength. Comparison is done for two materials to verify best material for spring in Shock absorber. Modelling is done in SOLID WORKS and here to increase the performance of the object different pitch values and different coil diameters were changed and analysis is done in ANSYS Workbench.

In this process transient analysis boundary conditions were applied on object and calculated deflection values and stress values, in this period of time which material will get into original position is consider to be best material in least time, (materials were chosen: mild steel (existing,), ss416, new material) finally thesis concluded with optimum pitch value with optimum coil diameter for optimum material, and after completing this process manufacturing the object, and then the process of manufacturing also discussing.
