High-speed impact test device for mechanically fastened joint and test method

The invention discloses a high-speed impact test device for a mechanically fastened joint and a test method and aims to solve the technical problem of poor practicability of the conventional test device. The technical scheme is that the high-speed impact test device comprises a stress wave amplifier, an induction coil, a discharge coil, a tension bar, a front chuck, a rear chuck, a pressure sensor, a workbench and a buffer board, and integration of an impact shearing device and an extension force test device is realized. The test method comprises a direct loading test method and an impact loading test method. The high-speed impact test device and the test method have the advantages that the impact speed is high, and impact load amplitude and pulse width are controlled precisely, and the practicability is good. Long-pulse and medium-low-velocity impact test loading is realized through direct loading, the impact speed range is 1m.s-50m.s, the impact pulse width is 0.5 ms-6.5 ms, narrow-pulse and high-ve
