The utility model relates to a static test device of an electrical parking brake system. The static test device comprises a test bed and a tensile force adjusting mechanism. The test bed is connected with the tensile force adjusting mechanism through a lever arm. The lever arm is pulled by a wire rope for simulation of the moment generated on a brake disc by a component force, which is downward along a ramp, of the gravity when an automobile is on the ramp. The test bed comprises a pedestal, a brake fixing support, an integrated parking brake assembly, a flange plate, a transmission shaft, a bearing pedestal, a double bearing pedestal fixing support and the lever arm. A motor is controlled by a test bed electronic control unit, a bevel gear reducing mechanism drives a screw rod and a nut to perform differential transmission, the wire rope is pulled and then the lever arm generates moment on the brake disc, so that the moment generated on the brake disc by the component force, which is downward along a ramp, o
