ANALYSIS OF EXISTING LEAF SPRING AND LEAF SPRING WITH VARYING THICKNESS AND WIDTH USING FEM

mechanical engieering

The main function of leaf spring is not only to support vertical load but also to isolate road induced vibrations. It is subjected to millions of load cycles leading to fatigue failure. In the present work improvement areas where more stress acting on the leaf spring one can improve the product quality while keeping the minimum cost. In the present work varying the thickness of leafs depending on the stress acting on the springs. The upper leafs of the spring get more stress then the bottom leafs. That way the project is modifying the leaf thickness, and width. The modified design was rectified conventional leaf spring’s problem. The modified leaf spring improved the fatigue life of the leaf spring. In this project two method of the modification was taken, first one was upper leafs are containing more thickness than the lower leafs thickness. Second method was upper leafs are containing more width than the lower leafs. The modified leaf springs ware modeling by SOLID WORKS, and analysis using ANSYS14.0.Software.
