The Crash-Box Crashworthiness Design Based on RCAR Tests

Abstract:

Based on the RCAR test standards, this paper analyzed the low-speed bumper tests regulations, proposed the design principles of the crash-box and identified the key parameters to evaluate the crashworthiness of the crash-box. This paper built the crash finite element models of the front bumper system, used the finite element analysis software LS-DYNA and HYPERWORKS to simulate the crashworthiness of the crash-box based on different thickness models and completed the performance study of the crash-box. The optimized crash-box has good crashworthiness and it will provide important guidance to the crash-box design.
