Crashworthiness Research for Bumper Beam of Vehicle Body Made of Different Materials

With vehicle safety regulations and the demand for vehicle lightweight are increasing gradually. The front bumper is increasing use of hot stamping or aluminum alloy. According the crash tests of base vehicle front bumper verify the validity of impact finite model. Complete front bumper crashworthiness analysis of a vehicle. Research front bumper made of high-strength steel, advanced high-strength steel, hot forming steel and aluminum alloy crashworthiness changes, by comparing, hot forming steel impact has the best crashworthiness, Aluminum alloy has best lightweight. Consider performance and cost, Front bumper using hot forming steel, the vehicle impact simulation analysis has been completed. Crash test results show that the results suffice development goals.
