摘要	This paper presents a damped metal-rubber vibration absorber modeled on the response of a coaxial dual-reflection space camera to random vibration. First, we analyze the metal-rubber structure and develop a corresponding metal-rubber damper. We then use finite element analysis (FEA) to develop a model of the space camera and perform a modal analysis and random vibration response analysis of the model. Finally, we verify the accuracy of the FEA via a sinusoidal-sweep vibration test and a random-vibration test. The test results demonstrate that, in the X, Y, and Z directions, the first-order natural frequency of a coaxial dual-reflection space camera equipped with the metal-rubber damper exceeds 100 Hz; this frequency is beyond the natural frequency of the satellite. Hence, the camera will resonate with neither the satellite nor the ground sinusoidal sweep vibration. The response of the coaxial dual reflection space camera to excitation in the X, Y, and Z directions is 4.98grms in the random vibration test; the vibration responses of a secondary mirror in the X, Y and Z directions are 3.381grms, 2.884grms, and 1.969grms, respectively. After the vibration test, no evident aberration can be observed in the system. The damped metal-rubber vibration absorber has a significant damping effect on the space camera and has a patent. 2021, Science Press. All right reserved.
