Short-stroke half-sine wave impact test bench

The invention provides a short-stroke half-sine wave impact test bench, and relates to the technical field of impact collision tests. The short-stroke half-sine wave impact test bench comprises a base, an air source, a support installed at the top of the base and an air path control system connected between the support and the air source. A plurality of groups of shock pads are mounted between thebase and the support; a double-pressure air cylinder is fixedly connected to the center of the support, an air cylinder rod is installed in the center of the double-pressure air cylinder, and a working table is installed at the top end of the air cylinder rod. A waveform generator is installed in the center of the inner surface of the bottom of the support. By designing a simple damping system, the impact force transmitted to the ground by the impact of the workbench can be greatly reduced, and the impact waveform is smoother, so that the experimental data is more accurate, and a higher descending speed can be obtain
