摘要	The support structure is a key component for connecting satellites and cameras to provide protection and space application requirements for cameras during launch and on-orbit surround stages. The vibration load of the deep space probe is 13 g (that of the earth exploration satellite is 8-9 g). The supporting structure should overcome the damage of the camera structure caused by the violent vibration and the thermal stability of the optical system, which has high design difficulty. In this paper, two different support forms of rigid foot and slider foot were designed by analyzing the structural characteristics of different support forms. The two kinds of support forms were designed from the balance of stiffness and thermal stability. The "A rigid foot+two flat foot" program was eventually adopted. The first-order frequency of the support structure is 58 Hz, which is much higher than that of the satellite base frequency. The simulation results show that the deflection angle of the primary mirror is 3.66, the maximum angle change of second mirror and third mirror relative to primary mirror is 7.85. They all meet the design requirements. Vibration and imaging tests show that the camera is working properly. 2018, Editorial Board of Journal of Infrared and Laser Engineering. All right reserved.
