Abstract
The goal of this research is to analyze vibration response when the main mirror in a Satellite Solar-B optical telescope assembly (OTA) is subjected to acoustic load. First, we determined the maximum frequency for the frequency range in this analysis from the results of vibration tests and acoustic tests. Next, we derived a frequency response analysis method using BEM, and calculated the internal sound pressure in the OTA. We then considered this internal sound pressure as the input, conducted a Power Spectrum Density (PSD) analysis using an FEM model, and analyzed the vibration response of the OTA. Results of these studies indicate good correlation between the results from the proposed simulation and the results of the acoustic test.
