  • The testing results of combustion chamber structure of hypersonic ramjet were used, which finished the analysis to structure random vibration response of combustion chamber shell. Meanwhile, both of them were compared ,which gave us a satisfied consequence. The analysis and technology method of random vibration response of vehicle complex structure were verified by this test. On the basis of that by taking advantage of pressure load data and analysising the random vibration response of combustor chamber in flight regime, the RMS(Root Mean Square) and PSD(Power Spectral Density) of acceleration response were presented, which was very important to the work of preliminary of dynamic environment of fight vehicle.
