Design and Analysis of Front Lower Control Arm by Using Topology Optimization

Mechanical Engineering

The lower control arm is a type of independent suspension used in vehicles. During the actual working condition, the maximum load is transferred from upper arm to the lower arm which creates possibility of failure in the arm. Hence it is essential to focus on the stress analysis of lower control arm to improve and modify the existing design. The present work will contribute in this problem by using finite element analysis approach. So, the main objective of this work is to model and to perform structural analysis of a lower control arm. The lower control arm is modeled in solid works software as per given specification in literature. To analyze the lower control arm, ANSYS FEA software is used. The standard modeled analyze and optimized using ANSYS topology optimization tool which is give most useful result in present. Using the topology shape optimization technique, the total deformation, von mises stress, maximum shear stress and mass will be reduced as compared to previous work. In this work also taken three types of materials for lower control arm i.e. EN24, Fe410 and Fe590. By reducing mass of the object and by suggesting the suitable material and design the production cost of lower control arm is reduced. This leads to cost saving and improved material quality of the product.
