摘要为了实现卫星的高精度姿态控制，需要对以辐射计为代表的大型回转载荷进行严格的动平衡设计仿真与试验。结合海洋二号卫星研制需求，在产品设计初期开展了针对微波辐射计的动平衡设计仿真，以提供优化产品结构和布局的依据。为了评估空气环境对动平衡配平的影响，进行了辐射计动平衡配平的风阻影响分析。考虑了重力因素、在轨热变形和无重力下轴承径向游隙变化对辐射计动平衡的影响。最终在真空环境下开展了针对辐射计的动平衡试验，以很小的配重质量，实现了微波辐射计的配平。

Abstract：

For high precision attitude control of satellite, the dynamic balancing design, simulation and test of large rotating payload have to be seriously treated. Combining with the research and development of HY-2A satellite, dynamic balancing design and simulation of microwave radiometer is conducted to provide the basis for structure optimization and layout design. Analysis of windage is conducted to evaluate its influence on dynamic balancing result. Also, the influence of gravity, thermal expansion and variation of bearing clearance has taken into account. Finally, dynamic balancing test has finished in vacuum environment and the dynamic balance target has achieved with very little adding weight.

Key words： Microwave Radiometer Large Rotating Payload Dynamic Balancing
