Dynamic and energy analysis based on bumper system low-speed collision test

The dynamic load strength test of bumper system is an important parameter for vehicle passive safety, but different test standards, different test requirements, which caused much trouble to the test authority. So dynamic and energy analysis based on bumper system low-speed collision test is very important. Build parameterized model of bumper system, analyse the dynamic characteristics and energy conversion characteristics when the bumper system low-speed collision occurs, which is based on the ADAMS virtual prototype technology. At the end of the paper we will use the test machine for the dynamic load strength trials of bumper system on the basis of three typical standards, whose result will compare with the below result that is analysed by ADAMS. According to the comparison, we can find the correctness of the simulation result is verified.
