摘　　要：介绍了挠性转子平衡问题的数学模型,分析了目前工程上常用的几种计算挠性转子平衡问题的方法的缺点,提出了基于最小二乘方法的扰动算法、直接修正算法和约束算法.这些算法在一定程度上改善了原来的工程上计算挠性转子平衡问题的方法的缺点.计算实例验证了基于最小二乘方法的扰动算法、直接修正算法和约束算法可以得到更满意的结果.The mathematical model for solving the dynamic balancing problem of flexible rotors is discussed first, the drawbacks of the main algorithms used in engineering are analyzed, and disturbing algorithm, direct modification algorithm and constrained optimal algorithm based on least-square method are presented, and these algorithms reduce the shortcomings of the existed approaches for solving dynamic balancing problems of flexible rotors. The experiments show that these algorithms could produce better results.
