| Abstract: | The analysis technique of the structure random vibration response excited by the base is described. The appropriate finite element model of the dummy satellite is created for simulating the vibration qualification ground test, and the response analysis on axial and transverse random vibration tests of the dummy satellite have been done based on the finite element model. By analyzing the root mean square(RMS), the cumulative mean square(CMS) and the power spectrum density(PSD) of the acceleration response, the random vibration characteristic of the dummy satellite and the performance of the satellite against the dynamic environment is assessed. The results obtained are useful in improving the design of the instruments and in providing some reference to the launch reliability of the satellite. |
