摘　　要：为解决现场动平衡计算中碰到的一些特殊的影响系数计算问题 ,采用矩阵的方法推导出最佳逼近意义下的影响系数求解的通式。该通式普遍适用于各种情况下的影响系数计算 ,最大限度地利用试加重及加重所得到的轴系动态响应信息。此通式易于实现计算机辅助平衡 ,为影响系数的计算、提炼及整理提供了一种强有力的方法。表 2参A general formulation using matrices for obtaining optimally approached influence coefficient has been derived for solving some special problems concerning the calculation of Influence coefficients, met with in on site dynamic balancing. This general formulation can be used for calculating influence coefficients for all conditions; it makes use, to the greatest extent, of rotor strings, obtained with trial added weights. It is helpful in realizing computer aided balancing, and herewith presents, itself as a powerful tool for calculating, abstracting and entangling influence coefficients. Tables 2 and refs 3
