Abstract

This paper presents, stress analysis of a ladder type cross over electric car chassis structure using FEM. The commercial finite element package SOLIDWORK was used for the solution of the problem. Two type of chassis was analysed, solid plate beam and porforated plate beam chassis. To reduce the weight of the chassis of the cross over electric car, the chassis structure design was modified by porforating the beam so that the main beam is not solid. The boundary conditions applied to this model of chassis can be classified into four general cases: static condition., the car climb 30o. the car is passed through a descend road about 30o and when the car is brake from 40 km/h until stop for 5 second. Output parameter analysed include stress, deflection and safety factor. It was concluded that porforate the plate beam reduce the chassis weight and did not have significant affect on the chassis safety factor, stress and deflection hence suitable for electric car.
