摘要	In order to improve the dynamic performance of inertially stabilized platform for aerial remote sensing and reduce the negative effect of vibration environment on image quality of electro-optical load, a topology optimization based on the variable density theory was studied. In the topology optimization of the inner frame of aerial remote sensing inertially stabilized platform, the minimum compliance of weighted structure was taken as an objective function, and the node deformation and volume ratio constraint were taken as response functions by using the software of NX/TOSCA. Based on the optimization results, the inner frame structure was designed, and it was analyzed with the software of NX/Nastran. The results of static analysis show that the maximum deformation of the inner frame structure is 3.5 m, which meets the requirements of the pointing error distribution. The modal analysis results show that the first-order natural frequency of the inner frame structure is increased to 334 Hz from 260 Hz, thus the stiffness of the inner frame structure meets the servo bandwidth's requirements. By the topology optimization design, the mass of the inner frame is reduced to 1.8 kg from 3.6 kg, which is beneficial to the realization of lightweight design. At last, the simulation analysis is verified by the pointing accuracy stabilized accuracy test and the flight test, which indicates that the topology optimization design of the inner frame is successful. 2015, Editorial Department of Journal of Chinese Inertial Technology.
