Study on the Head Impacting Properties of Foam Composite Material Engine Hood
The head impacting properties and the lightweight effect of a kind of foam composite material engine hood are studied in this paper. The finite elements model of headform impactor impacting the engine hood is created, LS-DYNA is used to do the simulation of impacting, the dynamic response of original steel material and foam composite material are simulated. The results show that using foam composite material can reduce the injury value of pedestrian head. In the end, the lightweight effect after using the new material is analyzed.
