An Overview of Disarray in Vibrational Analysis of Composite Leaf Spring Subjected to Harmonic Excitation with Nonlinear Parameters

Abstract

Most real-world phenomena exhibit nonlinear behavior. The behavior of steel leaf spring is nonlinear. It is having relatively high weight, and change in solid axle angle due to weight transfer specially during cornering of vehicle. That will lead to oversteer and directional instability under such situation it is very difficult for driver to control vehicle. These are some defect of metallic leaf spring so considering automobile development and importance of relative aspect such as fuel consumption, weight, ride quality, and handling development of new material is necessary in the automobile industry. In practice, engineering structures display a certain degree of nonlinearity, often due to a combination of nonlinear material properties, geometric effects, structural joints and nonlinear boundary conditions. Normally these effects are neglected by linearization in the intended working range. However, it becomes increasingly more important to take the nonlinear effects into account. This paper tries to give an idea about the previous researches and their finding about study of nonlinearity in spring.
