[0049] The specific working principle of this embodiment is as follows:
[0050] A wall body 4 is arranged on the top of the base, and the bottom of the wall body 4 is connected with the base through a hinge. The driving device 2 is arranged in the base and the bottom of the wall body 4. The motor 11 is connected with the winding device 13 through the shaft coupling 12, and power transmission can be realized.

[0052] The vibration machine 3 is arranged in the wall body 4, and the power supply and control signals are provided by an external control system.
[0053] During the tilting process, the winding device 13 releases a certain distance of the connecting rope 5, and the push rod 27 is started. The push rod 27 drives the scraping plate 21 to rotate around the rotating shaft 22 through the push-pull plate 23. The groove on the scraping plate 21 drives the sliding shaft 6 to rotate, so that the wall body 4 is tilted outward from the original vertical state.
[0054] During the returning process, the winding device 13 tightens the connecting rope 5, and the push rod 27 is retracted or kept. Under the traction of the connecting rope 5 and the cooperation of the push rod 27, the wall body 4 can return to the initial vertical position.
[0055] The wall body 4 will vibrate when simulating collapse, and the vibration is simulated by the vibration machine 3 arranged in the wall body 4. The vibration machine 3 can set different frequencies and amplitudes according to experimental needs, and generates periodic or random vibration after starting.
[0056] The vibration is transmitted through the wall body 4, and can be superimposed in the tilting or returning action, so that the real simulation of working conditions such as earthquake and impact can be realized.
