The invention discloses a rider collision test device. The device comprises an auxiliary supporting mechanism, a guide rail, a turntable and a movable supporting bottom plate; the auxiliary supportingmechanism is fixedly arranged on the guide rail; and the guide rail is rotationally arranged on the movable supporting bottom plate through the turntable; the guide rail is used for supporting a ridden vehicle and providing a straight running track for the ridden vehicle during a test; the auxiliary supporting mechanism is connected with the central shaft of the ridden vehicle so that the riddenvehicle can maintain balance during a carrying process; the turntable is used for driving the guide rail to rotate on the movable supporting bottom plate and locking the rotated guide rail; and the movable supporting bottom plate is used for moving the guide rail and the ridden vehicle to an arbitrary position and fixing the guide rail and the ridden vehicle. The rider collision test device of theinvention can be not only applied to ridden vehicles in different specifications, but also can meet the requirements of multi-angle collision of different vehicles, thereby realizing the study of theinjuries of a rider during a collision process.
