Earthquake torsional wave destruction tester

The utility model relates to an earthquake kink wave crash simulation experiment instrument, which can be used to simulate the occurrence of earthquake kink wave, belonging to the instrument for executing structural earthquake vibration simulation experiment. The utility model comprises a supporting frame, an experiment platform, an oscillator, a regulation and a control device and an instrument panel. The supporting frame comprises a vertical side frame, and a horizontal bottom plate; the edge of the experiment platform is fixed on the vertical side frame of the supporting frame; the oscillator is arranged at the lower part of the experiment platform, the upper end is closely connected with the experiment platform, the oscillator presents a cylindrical shape, and an impact vibration source is arranged inside; one end of the regulation and control device is connected with the oscillator, and the other end is fixed on the horizontal bottom plate of the supporting frame; the instrument panel is arranged on the side of the vertical side frame of the supporting frame. The experiment platform only vibrates but not shake as a whole when the experiment is performed, which can be used to simulate the occurrence, transmission, and destroy progress of an earthquake wave, and the utility model has the advantages of simple structure, low manufacturing cost, reliable working, and easy promotion and use.
