Abstract:
Shaker is adopted to simulate the shock environment in the test for parts of the liquid rocket engines. In the test, the shock time-domain waveform of shock response spectrum (SRS) is composed of sine wave, compound wavelet and Chirp wave. The sine wave composed shock spectrum is often used in China to perform the shock environment test of the liquid rocket engines. The shock time-domain waveform of SRS is composited according to the data extracted from shock time-domain signal in the liquid rocket engines testing. The calculated result proves that the algorithm is effective, and the composited shock time-domain data can meet the accuracy requirement of the
