A Durability Study on the Bumper of Mini Vehicle by Shape through Simulation Analysis

Objectives: Studies on aluminum alloy bumpers applied to vehicles are being actively carried out. This study aims at investigating the durability according to the compact car bumpers per shape. Methods/Statistical Analysis: In this study, two types of compact car bumper models were designed as 3D modeling and then simulation structural analyses were performed by the finite element analysis program of ANSYS. The durability of the bumper model of light passenger car by each configuration is investigated through this study. The analyses of structure and vibration on the bumper model of light passenger car by configuration are carried out. Findings: Although all comparison variables were shown to be smaller when the bumper model 1 was compared with the bumper model 2, the stress distribution was observed to be wider so that the reinforcement of material or the change of design for improvement is considered necessary. Through this study result, the deformation, equivalent stress due to natural frequency are investigated by each bumper model of light passenger car. According to the study results, the bumper model 1 exhibited a better durability compared with model 2, and hence is considered to be a safe and more suitable model for the vehicle application. The results are considered to be able to contribute to the development of more advanced bumpers having durability. Improvements/Applications: It is considered that the data obtained through this study can be utilized for the design of the bumper having an improved durability compared with the existing bumpers.
