提出了一种航空发动机多盘转子系统的平衡方法。提出了一种基于双重筛选的修正面选择方法，该方法考虑了平衡效果和配平重量等约束条件。第一次筛选以转子系统的平衡效果为目标函数，选择平衡效果较好的校正平面方案。第二次筛选的目的是筛选满足约束条件的配平重量。利用单位配平重量的平衡效果系数，得到了最优配平平面方案。采用双重优化方法对多盘转子进行了仿真和实验研究。结果表明，该方法能有效地抑制高速运转的多盘转子的振动。
This study proposes a method to balance the multidisk rotor systems of aeroengines. A double screening-based correction plane selection method with constraints, such as balancing effect and trim weight, is proposed in this work. The first screening takes the balance effect of the rotor system as the objective function, and the scheme of the correction planes with the better balance effect is selected in the first screening. The second screening aims to screen the trim weight that satisfies the constraints. The scheme of the optimal trim plane is obtained with the balancing effect coefficients of the unit trim weight. The double optimization method is utilized for the multidisk rotor in the simulation and experiment. Results show that the proposed method can suppress the vibration of multidisk rotors working at high speeds.
