本論文針對偏心多體轉子系統的動態特性分析，結合剛體、撓性體及破壞模擬的方法深入探討其在各種運行條件下的動力學行為表現。透過使用RecurDyn進行多體動力學分析，ANSYS進行模態分析，以及利用C# 開發專用的動平衡程式，本研究旨在處理及最佳化轉子系統的動態平衡。在研究的初期階段，通過RecurDyn對剛體和撓性體進行動力學模擬，詳細分析轉子系統在理想動平衡與非理想動平衡條件下的動態行為。此過程包括考量不同平衡塊在高速旋轉時對於接觸面的變形及其對系統整體穩定性和性能的影響。接著利用ANSYS進行模態分析以識別系統的自然頻率和振型，這對於預測和控制由偏心引起的不期望的振動是至關重要的。模態分析的結果有助於確定哪些結構模式易受偏心影響，以及如何通過結構調整來減少這些影響。
此外，開發的C# 動平衡程式允許操作者輸入實際測量數據，並即時計算所需的平衡調整，這一工具在系統最佳化和維護中發揮著重要作用，尤其是在工業應用中需要快速反應和精確調整參數情況。最後，本研究進行一系列基於RecurDyn的破壞分析模擬，以驗證理論模型的準確性和實用性。這些模擬結果顯示所提方法的有效性，並為系統的最終設計和最佳化提供堅實的數據支持。這項工作不僅增強我們對偏心多體轉子系統動態行為的理解，也為類似系統的分析和改進提供重要參考。

This thesis focuses on the dynamic characteristic analysis of the eccentric multibody rotor systems, integrating methods of rigid bodies, flexible bodies, and failure simulation to thoroughly explore its performance under various operating conditions. The study employs RecurDyn for multibody dynamics analysis, ANSYS for modal analysis, and C# to develop a dedicated dynamic balancing program, aiming to manage and optimize the dynamic balance of the rotor system.
In the initial stage of the research, dynamic simulations of both rigid and flexible bodies were conducted using RecurDyn, providing detailed analysis of the rotor system's dynamic behavior under ideal and non-ideal conditions. This process includes considering the deformation of different balancing blocks at high speeds on the contact surfaces and their impact on the overall system stability and performance.
Further, modal analysis was performed using ANSYS to identify the system's natural frequencies and mode shapes, which are crucial for predicting and controlling unwanted vibrations caused by eccentricity. The results of the modal analysis helped determine which structural modes are susceptible to eccentric influences and guided how structural adjustments could reduce these effects.
Additionally, the dynamic balancing program developed in C# allows operators to input actual measurement data and calculate the required balance adjustments in real time. This tool plays a crucial role in system optimization and maintenance, particularly in industrial applications where quick responses and precise adjustments are necessary.
Finally, a series of failure analysis simulations based on RecurDyn were conducted to validate the accuracy and practicality of the theoretical model. The simulation results demonstrated the effectiveness of the proposed methods and provided robust data support for the final design and optimization of the system. This work not only enhanced our understanding of the dynamic behavior of eccentric multibody rotor systems but also provided important references for the analysis and improvement of similar systems.
