Qiu Fang, Fu Qing Yang, Meng Meng, Zhong Wu Wang

Abstract

Double layer inflating safe cushion made of rubber and plastic or foam is developed to replace original foam inside bumper, the performance test of the designed safe cushion indicates the cushions advantage of lightweight and shrinkability, while the CAE simulated analysis proves that the cushion can protect pedestrians better and reduce the weight, showing a vast development potential.
