摘要

本文針對量測點及平衡面之位置，探討其對於提昇撓性轉子動平衡精度的影響。藉由線性系統中，以條件數度量系統靈敏度之方式，將其運用於影響係數法之最佳化，並且使用有限元素法模擬動平衡程序，得知平衡精度將隨著條件數的減少而顯著提昇。因此，本文以最小條件數為目標函數，使用禁忌搜尋法預先求得適當之量測點及平衡面位置，而得到殘振最小化，並以rotor kit之動平衡實驗驗證所提方法之有效性。

The influences of locations of measurement sensors and balancing planes on accuracy improvement for balancing of flexible rotors are investigated. Generally, the condition number is used to evaluate the sensitivity against disturbances for a linear system. In this study, the optimization of the influence coefficient method is implemented by using the minimum condition number. The balancing procedure of flexible rotors is simulated by utilizing finite element method. The balancing accuracy can be improved as condition number of influence coefficients decreasing. Thus, the condition number is served as an objective function by using tabu search to seek the creditable locations of balancing planes and/or measurement sensors in advance for the determination of minimum residual responses. The proposed method is verified by the experiments of balancing a rotor kit.
