Abstract

In the current development of bumper systems for the automotive industry, the standard car bumpers are mostly made of polymer or fiber like Polypropylene, ABS Plastic and Glass fiber. The car bumper is designed to prevent or reduce physical damage to the front and rear ends of passenger motor vehicles in low-speed collisions. In this research, the frontal bumper of the Proton Wira will be analyzed under a low-speed collision. The main objective of the project is to analyze the effect on Wira frontal bumper under a static load and improve the design to overcome the weakness of the existing bumper. The changing characteristic of the bumper will be the main result to be considered in this project, because at the end of this project it will be some improvement to be made through the design of the Wira Bumper. In this project Finite Element Method (FEM) is used in order to make the analysis, simulation and modeling of frontal bumper of Wira easier. The Finite Element Method will be used to predict displacement and von mises stress of the bumper during the low-speed collision under the specified load. This is to find the lack of stiffness or the elastic of the bumper using the static load as the impact force. In design process and redesign of the bumper model for this project, the CATIA software will be used to create 3D model of Wira frontal bumper. Mean while the MSC Nastran and Pastran software will be used to analyze the bumper under the specified characteristic. The 3D model of Wira frontal bumper will be analyze under the impact of static load in criteria of low speed collision impact test order to gain the suitable result.
