Impact fatigue test equipment

The invention discloses impact fatigue test equipment. An impact rod, a first drive coil, a secondary coil and a second drive coil are sequentially arranged on one side of a test board fixing support of the equipment, a test piece fixing frame is arranged on the other side of the test board fixing support, a test piece is fixed on the test piece fixing frame, and an H-bridge current commutator is electrically connected with the first drive coil and the second drive coil. The H-bridge current commutator is used for changing the magnetic pole directions of the first driving coil and the second driving coil by controlling the current directions of the first driving coil and the second driving coil, so that the secondary coil moves under the action of magnetic field force, and collision and resetting are realized; and the control system is electrically connected with the H-bridge current commutator, and is used for setting parameters, controlling the turn-on and turn-off time of the H-bridge current commutator ac
