The lower control arm is a unique type of independent suspension used in automobile vehicles. During the actual working condition, the maximum load is transferred from upper arm to the A arm which creates possibility of failure in the arm. Hence it is essential to focus on the stress analysis of A suspension arm to improve and modify the existing design. A suspension arm is an important part used in a suspension system of a car suspension arm performance a major role in managing the motion of the wheel during bump, turning, and breaking. This paper proposed the design optimization and model analysis of steel cast for the front A suspension arm was investigated. CATIA software was utilized to design the suspension arm. ANSYS 19 software was also used for analyzing the structural strength and optimize the parts weight. The target of the new design was a 20% weight reduction from the existing part fabricated using steel material. Testing and validation of new design using FEA analysis. Modal analysis carried out to find out natural frequencies of A suspension arm and validation are done with the help of Static Structural Analysis using ANSYS software, Impact Hammer Test & UTM.
