摘要
进行转子的现场动平衡需要求解复数方程组,该方程组的系数是由施加配重的情况决定的。本文将该方程组正规化后,讨论其系数矩阵的谱条件数,得到在二平面和多平面影响系数法中施加配重对解的稳定性的影响情况,并获得一些有实际意义的结论。
It is required to solve a set of complex simulanuons equation when balancing the on-line rotor. The coefficients of the equations are dependent on the situation of the test weight. By transforming the equation group into a canonical form, and discussing the spectral condition number of its coefficient matrixe, in may become clear how the test weight influences the stability of the equation group's solution. Some practical conclusions are thus presented.
