TRANSIENT ANALYSIS OF IMPACT LOADS ON BUMPER BEAM AT DIFFERENT OFFSETS

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 validate a modeling procedure for the system’s crash performance. The experimental database was used for the development and validation of modeling procedures for the crash performance of the bumper beam-longitudinal system with the use of the FE-code ANSYS-DYNA. The numerical model should be able to predict the collapse mode with a high level of certainty in order to ensure robust design.
