description The invention relates to an engine simulation test technology, in particular to an engine rotating speed fluctuation simulation device and a test method, and aims to solve the problems that in a knocking abnormal sound test caused by engine rotating speed fluctuation, the test and verification progress is slow due to vehicle model coordination, test space limitation and disassembly and assembly reasons in a whole vehicle test; and the process is troublesome. The device comprises a bottom plate, a driving motor, a motor bearing seat, an offset transmission shaft, an intermediate bearing seat, acoded disc, a horizontal transmission shaft, a speed changer, a fixed flat plate, a movable flat plate, a driving unit, a sensor assembly and an information collecting and processing system, and rotating speed fluctuation is simulated when the offset transmission shaft deviates by a certain angle to rotate. The invention further provides a test method of the simulation device, after the rotatingspeed sensor signal and th
