description The invention discloses an automobile rear suspension trailing arm dynamic test device which comprises a support, a fixing frame is fixed at one end of the support, and a connecting shaft sleeve is connected in the fixing frame through a load pressure assembly. A guide rail is fixed at the other end of the support, a sliding table is arranged in the guide rail in a sliding mode, and a longitudinal arm to be tested can be hinged between the sliding table and the connecting shaft sleeve. A rotating shaft rotatably penetrates through the connecting shaft sleeve, the two ends of the rotating shaft are connected to the two sides of the support through radial restraining assemblies respectively, and one end of the rotating shaft penetrates through the radial restraining assemblies to be connected into a driving motor. Compared with the prior art, the device can simulate working conditions of different sprung loads and working conditions of different frequency vibration of the trailing arm, and can adjust the magnit
