摘要
本文提出用复模态影响系数来解决转了大衡的在线以别和诊断问题，讨论了影响系数矩阵的力学意义．试验中可不加试重求出影响系数，并编制了相应的计算程序．
This paper presents a method of complex modal influence coefficient to solve the problems or fault diagnosis and on line identification of the unbalanced loads for a rotor. The mechanical significance of the influence coefficient matrix is dealt with.The influence coefficients are determined without adding test weights .Finally a related calculative programme is worked out .
