Design, Modeling and Structural Analysis of Wave Springs

Abstract

AbstractWave springs are precise flat wire compression springs that fit into assemblies that other springs cannot since the overall lengths and operating heights of Wave springs are lower than those of conventional round Wire springs, they will often reduce the size of an assembly by as much as 50%. Of course, this will also reduce the part weight and raw material cost of every spring produced. Wave springs operate as load bearing devices. They take up play and compensate for dimensional variations within assemblies. A virtually unlimited range of forces can be produced whereby loads build either gradually or abruptly to reach a predetermined working height. This establishes a precise spring rate in which load is proportional to deflection. Functional requirements are necessary for both dynamic and static spring applications. Special performance characteristics are individually built into each spring to satisfy a variety of precise operating conditions. Typically, a wave spring will occupy an externally small area for the amount of work it performs. The use of this product is demanded, but not limited to tight axial and radial space constraints. In this paper, a three dimensional finite element (FE) model for shock absorber spring is proposed. The present work deals the structural analysis for modelling the structural behaviour of wave springs. The design of spring in suspension system is very important. In this work a wave type of spring is designed and a 3D model is created using Pro/Engineer. The model is also changed by changing the length of the spring. Structural analysis has been conducted on the wave spring by varying the spring material such as Structural steel and Beryllium Copper. For this analysis, loads are considered as bike weight, single person and two persons. Structural analysis is done to validate the strength. The present study makes an attempt to compare the results for selecting best material for springs
