The invention discloses a trolley test method for simulating offset collision. The trolley test method for simulating offset collision comprises the steps of: (1), obtaining the test waveform and thedummy damage value of a whole vehicle offset collision test, establishing a whole vehicle simulation offset collision model, then, inputting the test waveform of whole vehicle offset collision, so that the dummy damage value of a simulation model is obtained, and adjusting the white body angle in the whole vehicle simulation offset collision model till the simulation precision is minus 5-5%; (2),adjusting the white body angle of a trolley according to the white body angle obtained by the whole vehicle simulation offset collision model, inputting the test waveform of the whole vehicle offset collision into a trolley control system, and performing iteration of the test waveform till the iteration precision of the trolley waveform is minus 3-3%; and (3), performing constraint system test matching verification of the trolley, obtaining the trolley simulation precision through a formula, and, if the trolley simulation precision is minus 5-5%, performing subsequent offset constraint systemoptimization verification through the trolley. The trolley test method for simulating offset collision disclosed by the invention is simple to operate, high in practicability and reliability, and adjustable in collision angle.
