Pendulum impact test equipment cannot meet the high magnitude test demand of large products. This paper designed a pneumatic impact test which can make a high-magnitude impact test, giving the design principle of the pneumatic impact test system, introducing the design methods of the pneumatic test system. The test results show that the technical indexes of the system meet the design requirements. The pneumatic impact test system with a 1.25 m× 1.25 m table based on the shock response spectrum principle can realize the inflection frequency adjustable from 500 to 1500 Hz and the slope adjustable from +6 to +9 dB. And it can realize the shock response spectrum test of 5000g magnitude at full load. The test system can meet the current test magnitude and test requirements of spacecraft products. The method proposed in this paper can serve as a reference for the design of this kind of impact test systems.
