The invention relates to an overload environment simulation test device and particularly relates to a dual-overload environment force loading simulator. The problems of inconvenience in use, a large size, high cost, large vibration in a test and a limited application range of an existing overload environment simulation test device are solved. The dual-overload environment force loading simulator comprises a flywheel energy storage part, a shock overload environment force loading part, and a rotation centrifugal overload environment force load part. The flywheel energy storage part comprises a cylinder, a master rotation shaft, an electromagnetic clutch, a couler, a motor, a conductive sliding ring. The shock overload environment force loading part comprises a ring-shaped upper rotation disk, a ring-shaped lower rotation disk, an electromagnet, a collision block, and a position sensor. According to the dual-overload environment force loading simulator, the impact overload of aircraft key components and the continuous loading process of rotation centrifugal overload environment force are simulated truly, and the device is suitable for the fields of the performance test of an aircraft, a shock test of a material, and the calibration of an acceleration sensor.
