摘　　要：针对空间用谐波减速器的传动性能受多种因素影响且这些因素又相互作用的实际情况,选用XB1-60-150型谐波减速器,采用交互正交试验方法,进行了谐波减速器传动性能热真空试验,考察了转速、环境温度、负载扭矩和润滑方式等因素及其耦合作用对谐波减速器传动效率的影响。通过极差分析和方差分析研究了各因素及其耦合作用对传动效率的影响敏感性,两种分析方法得到的试验结果一致。结果表明,在置信度p=99%时,转速和环境温度对谐波减速器传动性能有显著影响,且负载扭矩与润滑方式之间的交互作用高度显著;交互作用分析获得了谐波减速器最佳的空间使用条件,在该条件下谐波减速器的传动性能最优。In view of the multiple factors and their interactive influences affecting the transmission performance of harmonic drives used in spacecraft,thermal-vacuum tests are performed using harmonic drive of type XB1-60-150.Based on the interactive orthogonal design method,the effects of rotational speed,surrounding temperature,output load torque,and lubrication type on the transmission efficiency of the harmonic drive are investigated.Range analysis and variance analysis are applied to analyze the sensitivity of these factors and their coupling influences.The results achieved by both range analysis and variance analysis are close.When confidence p=99%,the study indicaties that rotational speed and surrounding temperature have notable effect on the transmission performance of harmonic drive,and so do the interactive influences of output load torque and lubrication type.The best application conditions are obtained by interactive analysis under which the transmission performance of harmonic drive can achieve the most satisfactory effect.
