摘要	In order to solve the random vibration acceleration response of a high resolution space camera, the main support structure of the space camera was optimally designed. A mathematical model was established based on random vibration responses, and the random vibration root-mean-square response expression was deduced. Then, the camera supporting structure was designed by virtue of the principle of three point location and the idea of bipod flexible structure. Taking the RMS of acceleration response as an objective function and the natural frequency as a constraint, the sizes of the support structure were optimized. The position of the flexible link was also optimized. Using the MSC.Patran Nastran finite element software to analyse the support structure, it is shown that the RMS of random response at the camera installation point is less than 19.6 grms. Finally, the camera support structure was tested under random vibration excitation. The results show that the maximum relative error of the random vibration response between the analysis result and test result is 8.2%.The performance parameters of the main support structure can meet the requirements of space camera, and the feasibility of the optimization method was verified. 2017, Editorial Office of Journal of Vibration and Shock.
