Dynamic Analysis of an Lower Control Arm Using Harmonic Excitation for Investigation Dynamic Behaviour

EasyChair Preprint 5933

Abstract

In the automotive industry, the riding comfort and handling qualities of an automobile are greatly affected by the suspension system, in which the suspended portion of the vehicle is attached to the wheels by elastic members in order to cushion the impact of road irregularities. Suspension arm is one of the main components in the suspension systems. It can be seen in various types of the suspensions like wishbone or double wishbone suspensions. Most of the times it is called as A-type control arm. It joins the wheel hub to the vehicle frame allowing for a full range of motion while maintaining proper suspension alignment. Uneven tire wear, suspension noise or misalignment, steering wheel vibrations are the main causes of the failure of the lower suspension arm. Most of the cases the failures are catastrophic in nature. Hence, it is reported that the structural integrity of the suspension arm is crucial from design point of view both in static and dynamic conditions. Finite Element Method (FEM) gives better visualization of this kind of the failures.

Keyphrases: FEA, FFT, LCA, Wishbone, frequency, harmonic, impact, lower control arm, suspension, vibrations
