Safety belt and airbag play very important roles in traffic accident. During the development of the restraint systems such as safety belt, airbag and so on, a large part of full-scale impact tests can be replaced by sled tests in order to cut material costs and shorten the design cycle. According to the energy-absorbing feature of steel bar, a new steel bar energy-absorbing type frontal impact sled test system that is used to simulate the frontal impact deceleration history is designed. This system simulates the full-scale frontal impact deceleration pulse by adjusting steel bar's array, number, length, and disengagement or no. Simulation results that based on this system shows the deceleration from simulation test complies with the requirements of the frontal impact regulations such as CMVDR294, FMVSS208, ECER94 and so on, that is, the difference of velocity pulse between sled test and relevant full-scale impact test is within ± 1m/s.
