摘　　要：为降低微振动对多载荷集成小卫星的性能影响,提出卫星隔振方案,并建立多载荷微振动集成分析模型,以评估微振动抑制效果。首先,开展了从振源到载荷的两级被动隔振方案设计;其次,建立线性光学系统像移与光学元件运动关系,考虑光学载荷对微振动敏感度的差异性;进一步建立了包含不同光学载荷的微振动集成分析模型,计算卫星隔振前后综合像移;最后,开展地面微振动测量试验和在轨推扫成像校验。结果显示:集成分析模型计算出的最大综合像移值小于0.25像素,地面试验中激光和相机主镜振动最大峰-峰值分别为0.05″和0.012″,在轨成像光学相机频域内最大像移值为0.061像素。地面和在轨微振动测量数据验证了隔振系统设计和集成分析模型的有效性。In order to mitigate the impact of micro-vibration on the performance of the multi-load integrated small satellite,the paper proposes a satellite vibration isolation scheme and establishes an integrated analysis model for multi-load micro-vibration to evaluate the suppression effect.First,a two-stage passive isolation scheme from the vibration source to the load is designed.Second,the relationship between image shifts is established for the linear optical system and the optical element motion,and then the micro-vibration integrated analysis model with different optical loads is established to account for the difference of sensitivities of optical loads to micro-vibration.The comprehensive image shifts before and after the satellite vibration isolation are calculated.Finally,both the micro-vibration measurement test on the ground and the push-scan imaging verification in orbit are carried out.The results show that the maximum integrated image shift calculated by the integrated model is less than 0.25 pixels,the maximum peak-to-peak vibration values for the laser and camera's primary mirror in the ground test are 0.05″and 0.012″,respectively,and the maximum image shift value in the frequency domain for the in-orbit imaging optical camera is 0.061 pixels.Both the ground and in-orbit microvibration measurement data validate the effectiveness of the vibration isolation system design and the integrated analysis model.
