Abstract—For the vibration response problems of aerospace thin-walled structure under thermal-acoustic excitation, combined with the theory of structural-acoustic coupling, analyze dynamic response characteristics of thin-wall rectangular plates with four edges clamped, and doing comparative verification between simulation results and test results. Meanwhile, based on different loading ways: diffusion field, progressive wave, study the stress/strain response rule of structure under the different loading combinations between SPL and temperature. Respectively analyze the structure stress/strain response’s sensitivity to temperature under different acoustic loading ways. The results of the analysis will provide a reference to determine the reasonable fatigue life prediction model, and also provide an important reference for a new generation of aviation engine structure design.
Index Terms—Thin-walled structure, thermal-acoustic loads, vibration response characteristics, acoustic vibration coupling theory.
