摘要
控制力矩陀螺是空间站的关键姿态控制部件,也是空间站的主要噪声源.对1000N.m.s控制力矩陀螺的噪声进行了详细测试,测试结果表明1000N.m.s控制力矩陀螺的最大噪声值达到90.9dB.对测试结果进行了分析,确定了主要噪声源及其作用机理,为后续降噪工作奠定了基础.
The control moment gyroscope(CMG) is one of the important actuators for attitude control,and it is also the main noise source of the space station.The noise of 1000N · m · s CMG is completely tested,and the results show that the maximum noise of the 1000N · m · s CMG reaches 90.9dB.Based on the analysis of the noise testing results,the main noise sources and their action mechanism are determined,which provides the theoretical basis for the subsequent study of the de-noising method.
