PURPOSE: A double shock wave inspecting device is provided to effectively inspect the shock resistance of equipment receiving double shock waves. CONSTITUTION: A double shock wave inspecting device comprises a speed generator assembly (1) and a trolley assembly (2) for collision. The speed generator assembly is operated by oil pressure or air pressure and generates a required speed by pushing a piston with high pressure. The trolley assembly for collision collides with a test bed (3) at a high speed, thereby generating positive acceleration, which is a primary waveform, by a spring. The trolley assembly for collision collides with a secondary waveform generator assembly (4), thereby generating negative acceleration, which is a secondary waveform, by the spring and a variable damper type waveform regulator assembly (5) operated by oil-and-air pressure or an MR fluid.
