Optimization of the Frontal Rail Based on Composite Material


Article Preview

Frontal rail constructed of composite material was researched, in order to improving vehicle safety performance in frontal crash as well as lightweight of vehicle. Compliance to FMVSS 208, the vehicle frontal crash was simulated using the finite element model of the full vehicle. The occupant head injury was analyzed by sled test using crash pulse. Then, the composite material parameters which have the best function of reducing the occupant head injury value were studied by using orthogonal test method. Using this kind of composite materials, the occupant safety protection was effectively improved and the weight of the frontal rail was greatly reduced.
