Design and Analysis of Chassis Frame for Two Wheel Electric Commercial Vehicle

Abstract

The chassis frame forms the backbone of a vehicle; its principal function is to safely carry the maximum load for all designed operating conditions. Automotive chassis is the main carriage system of a vehicle. The chassis serves as a skeleton upon which parts like gearbox and engine are mounted. The two-wheeler chassis consists of a frame, suspension, wheels and brakes. The chassis is what truly sets the overall style of the two-wheeler. Commonly used material for two-wheeler chassis is steel which is heavy in weight or more accurately in density. There are various alternate materials like aluminum alloys, titanium, carbon fiber, magnesium, etc. which are lesser in weight and provide high strength and thus can be used for chassis. The frame consists mostly of hollow tubes and serves as a skeleton on which components like the fuel tank and engine are mounted. This project deals with design of two-wheeler chassis frame and its weight optimization. Various loading conditions like static loadings were carried out on the chassis and the structural stability of the chassis is analyzed by using alternate material as well as alternate geometry while maintaining the strength. Geometry modification in present chassis design by changing thickness of hollow tube. The various materials are studied and the best material will be selected as the solution. The weight optimization is achieved in this project. The 3d model of the chassis is created using appropriate modelling software. And its structural behavior is analyzed using Ansys Workbench 2022R1. Key Words: Weight Optimization., Chassis Frame, Structural Stability, 3D Modelling.
