To develop a shock response spectrum test facility for testing space products in the pyrotechnic environments.The natural frequencies of the resonant plate, a key part of the facility, were calculated with finite element method. The dynamic response of the whole system was simulated when the machine was excited by a real shock generated by a dropping hammer. A shock response spectrum test facility was developed under the guide of the simulation results.The resonant plate drop machine could simulate pyrotechnic shock by adjusting the force, the natural frequencies of the plate and the damping materials above and under the plate.The agreement between the measurement and the simulation indicates that the computer simulation results are reliable. It is feasible to use the resonant plate drop machine to simulate pyrotechnic environment.
