DESIGN ANALYSIS OF BUMPER BEAM SUBJECTED TO OFFSET IMPACT LOADING FOR AUTOMOTIVE APPLICATIONS

The bumper beam is fixed to front portion of the automobile structure and it is one of the primary component which undergoes damage and transfers the forces to the rest of the structure. Thus the modern bumper beam systems should play a key part in the safety concept of an automobile, ensuring that minimal accelerations are transferred to the passenger. Further the automotive producers are demanding for robust bumper beam systems showing good and reproducible impact behavior. The objectives of this study were to increase the physical understanding of the different phenomena taking place during the offset impact of an automotive bumper beam-longitudinal system as well as to valid ate a modeling procedure for the system’s crash performance.
