| 英文摘要 | Considering the low stiffness and strength for cantilever motor on the pitching shafting of a wide-angle aurora imager, a solution is proposed for setting up the motor-auxiliary-support, a stiffened plate, between the base and the motor. Firstly, the material, support position and structure form were determined. Secondly, the structural topology optimization was accomplished from the layout of stiffeners and the parameters of stiffeners by using the finite element simulation method. Then the structural design of the motor-auxiliary-support was determined. The simulation analysis and mechanical tests of the camera were carried out. It was found that the finite element analysis results were in agreement with the test results. After installed the motor-auxiliary-support, the frequency of the camera was increased by 14.58%, and the acceleration response of the sinusoidal vibration test on the motor was decreased by 79.32%. The structural ability to resist space mechanics environment had been improved significantly. The motor-auxiliary-support had a remarkable effect on improving the stiffness and strength of the structure. |
