【摘要】 在最小二乘影响系数法动平衡中，由于计算中有求逆过程，因而可能引起计算所得平衡质量缺乏适定性，引起平衡失败，为解决这一问题，引入了截尾奇异值分解技术（TSVD），实践证明平衡效果是好的。更多还原

【Abstract】 because one has to determine the inversematrix in application of least -square influence coefficientmethod, the calculated balancing mass may not be suitedto field condition and may cause balancing failure. In order to solve the problem, a truncated singualr value decomposition technique is presented in this paper. ThePractice proved that the method is successful in the application of rotor balancing.更多还原
