Abstract

Automotive bumper beam system plays a very important role not only absorbing impact energy but also in a styling stand point. A great deal of attention within the automotive industry has been focused upon light weight, sufficient safety and also less material used in recent years based on optimization design. Topology optimization technique was used to optimize bumper beam design. For this project Perodua Myvi bumper beam was selected as the case study. An overview of topology optimization procedure and some closely related subjects in automobile industry focused on bumper beam design explained in details in this report. The bumper beam design was optimized base on topology optimization technique and the outcome is four concept design were developed using SolidWorks software. The optimized design then analyze regarding the impact performance using COSMOSWORKS Designer analysis software. From the analysis results then the four design concept have been compared to select the best optimized design base on the optimization study which defined by objective function, design variable and constraints. It was found that design concept 2 is the best optimized design because it fulfills the optimized study criteria. Finally, the application of topology optimization during the development process of an automotive bumper beam is discussed, including identification of its major benefits.
