Two-point excitation air cannon impact test system

The invention relates to a two-point excitation air cannon impact test system, which comprises two air cannon, a support structure, a resonant plate, a cushion block and a test tool, the air cannon comprises an air path integrated control system and a synchronous controller, the support structure is fixedly connected with the resonant plate, the test tool is fixed on the resonant plate through the cushion block, and the cushion block is fixed on the support structure. The two air cannons are respectively arranged under the test tool, the two air cannons are respectively pressurized through the gas circuit integrated system, the pressurizing process of the gas circuit integrated system can ensure that the pressure released by the two air cannons is completely the same, and the synchronous controller controls the air cannons to synchronously drive the air cannonball to impact the resonant plate, so that a two-point excitation impact test system is formed. The problem that a large-size product cannot be subjecte
