- 1. DESIGN AND ANALYSIS OF SHOCK ABSORBER SPRING FOR AUTOMOBILES GUIDED BY Mr. D.N.Graceson, M.E., Assistant Professor Department of Mechanical Engineering PRESENTED BY Jobin.R.A 961618114018 Nandan.B.R 961618114020 Nisanth Kumar.P 961618114021 Marthandam College of Engineering and Technology, Kuttakuzhi.
- 2. ABSTRACT Shock absorber is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. In a vehicle, it reduces the effect of traveling over rough ground, leading to improved ride quality, and increase in comfort due to substantially reduced amplitude of disturbances. In this project suspension system is design and a 3D model is create using Creo. The model is also change by changing the thickness of the spring.
- 3. Structural analysis and modal analysis are will do on the shock absorber by varying different spring materials. Spring materials are Spring Steel, Phosphor bronze, Beryllium Copper and Titanium alloy. To validate the strength of the model, the structural analysis on the helical spring was done. The analysis is done by considering loads, bike weight, and single, double riding. Finally comparison is done for different materials to verify best material for spring in Shock absorber. Modeling is in Creo and analysis is in ANSYS.
- 4. INTRODUCTION A shock absorber or damper is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. Shock absorbers are an important part of automobile and motorcycle suspensions, aircraft landing gear, and the supports for many industrial machines. Large shock absorbers have also been used in structural engineering to reduce the susceptibility of structures to earthquake damage and resonance. A transverse mounted shock absorber, called a yaw damper, helps keep railcars from swaying excessively from side to side and are important in passenger railroads, commuter rail and rapid transit systems because they prevent railcars from damaging station platforms.
