英文摘要	A series of double-axis flexible support structure is put forward to ensure the surface figure and stability of the miniature space camera ultra-light reflectors. Taking the ultra-light mirror surface under multiple operating conditions as the goal, the integrated optimization method is used to optimize the support structure, and the statics of the optimized structure under the self-weight and temperature conditions are analyzed. The root-mean-square of each condition is within 3.5 nm, which is far better than the design requirement. The adhesive strength of the developed mirror assembly was checked and the dynamic performance was analyzed by finite element method and test. The bonding area of flexible support structure and mirror is 1 138 mm2. The basic frequency of the X, Y and Z directions of the mirror assembly is above 500 Hz. The relative error of the test and analysis results is less than 6.5%, which verifies the correctness of the finite element analysis model. At the same time, it shows that the series of double-axis flexible support structure design is reasonable, and the integrated optimization method is reliable. 2018, Science Press. All right reserved.
