Abstract: When the vehicles impacted in low speed, it s' frontal bumper is useful to protecting itself. But the protecting capability needs to be indeed evaluated. According by ECE R42 regulation, frontal bumper model is established by HyperCrash, nonlinear simulation analysis is carried out by RADIOSS to evaluate the crash performance of the rear bumper.
