RRRCC繞線機構動態平衡之研究

本研究之目的在於提出RRRCC型自動定子內繞線機之動態性能改善之最佳化方法，以降低機構之輸出加速度、搖撼力、及搖撼力矩。首先，以二元數矩陣法與D-H矩陣進行運動分析，先求出各接頭之角位移、角速度、及角加速度，再求出各桿件質心之位移、速度、以及加速度。接著，以動力學原理，求得機構各桿件之搖撼力與搖撼力矩。然後，先以輸出桿加速度最小為目標函數，進行變轉速輸入曲線之設計，再以搖撼力與搖撼力矩最小為目標函數，分別進行質心位置與變轉速輸入函數之最佳化設計。最後，進行模擬，以驗證所提設計方法之效果。由結果顯示，所提出之方法可有效降低輸出加速度、搖撼力、及搖撼力矩。因而可提高其運轉速度、加工精度、以及機器壽命，並減少噪音與震動。

This paper aims to propose a systematic approach for minimizing the output acceleration, the shaking force, and the shaking moments of the coil winding mechanisms of RRRCC type. Firstly, dual number notation is employed for conducting kinematic analysis. Then, the shaking forces and the shaking moments of the winder are formulated by the theory of dynamics. Finally, optimal approaches for minimizing the shaking forces, the shaking moments and the output accelerations, and three examples are given for illustration. The results show that the proposed approach can significantly reduce the output acceleration, the shaking force, and the shaking moments, therefore the operating speed, winding accuracy, service life, and vibration of the winder could be enhanced.
