Investigation Optimise Parameter of Upper Control Arm for Mining Breaker

Abstract

Suspension system of automobile is always responsible for safety and driving comfort as the suspension carries the entire vehicle body and transmits all forces between road and body. Suspension system absorbs the vibrations due to rough terrains or road disturbances. Suspension system also provides stability under different conditions like accelerating, uneven road, cornering, braking, loading and unloading. for the vehicles of mining there is no such a suspension system exist as they stands at single point very long, to provide suspension system for the portable mining Breakers as lots of fatigue to human worker working with it. Control arm is important part of suspension system as it joints steering knuckle to vehicle frame. In automotive industry structure optimization techniques was used for light weight and performance improvement of modern new cars. However, static load conditions could not represent all the various situations of automobile parts which subjected to complex loads those varying with time, especially in case of crusher and for lower control arm of front suspension. This paper deals with transient structural analysis of the upper control arm of double wishbone suspension and modal analysis was carried out using ANSYS software for the mining Breaker. Optimization of upper control arm was carried out by selecting better material for weight reduction and better strength. Testing was carried out on Universal testing machine to validate analysis results.
