Objective: To develop a shock response spectrum test facility for testing space products in the pyrotechnic environments.
Method: 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.
Result: 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.
Conclusion: 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.
