description The invention is applicable to the test verification field, and provides a sled test method for simulating an auto frontal impact and a sled. The sled comprises a basic trolley, an auto carling, a subframe, an upper body and a rigid power assembly. The sled test method comprises the following steps: A, a mule car CAE simulation impact model is built; B, according to the mule car simulation impact model, an equivalent sled CAE simulation impact model is made; C, simulation data analysis is carried out on the mule car simulation impact model and the sled simulation impact model; and D, a simulation data analysis result of the sled simulation impact model and a simulation data analysis result of the mule car simulation impact model are benchmarked, if consistent, the sled is tried and assembled for impact test verification, and if not, simulation analysis and benchmarking are carried out on the sled simulation impact model again. Thus, the problems of difficult test sled processing, high cost and long preparatio
