Structural Validation and Optimization of Truck Chassis Using Finite Element Analysis

Abstract

The chassis of a truck is a crucial component and it acts as a framework for the body and other components of the truck. Additionally, it must be sufficiently robust to handle pressures such as shock, twisting, vibration, and others. Having sufficient bending stiffness for improved handling characteristics is just as vital as strength when designing a chassis. Deflection, maximum stress, and maximum equilateral stress are crucial design factors for the chassis. The work done to optimise the truck chassis is what this project. To determine stiffness and determine how to minimise weight while increasing stiffness, sub-modelling and static analysis is performed. Therefore, using real parameters, a correct finite element model of a truck chassis must be created. Applying appropriate loading and boundary constraints to the truck chassis model. For Finite Element Analysis, pre-processing is done on the Hypermesh 21.1 and analysis is carried out in Optistruct package.
