Analysis and Optimization of a Helical Compression Coil Spring used for TWV

Mechanical Engineering

Suspension system of three wheeled vehicle (TWV) consists of springs as well as hydraulic shock absorber which is usually designed for passenger’s safety and to improve passenger’s comfort. There is literature review of some papers was done in this paper which was related to the design and analysis spring. Helical compression springs are commonly used in the most of the automobile vehicle. Most automobile company now days have interest in the reduction of spring weight without changing the remaining system. For this reason in present paper the numerical method and finite element analysis was used for the selection of minimum number of coils. Using modeling software solid works completed the modeling and by using Ansys software meshing and post processing of spring was done. For validation purpose comparison of software and theoretical values was done. For this load verses deflection values were calculated. The main aim of this paper is to suggest the alternate minimum number coils for helical compression spring which used for three wheeler and reduce the weight of the existing coil spring.
