滾子凸輪機構目前廣泛應用於工業之中，然而在高速運作下，其動態特性將對其精度產生很大的影響。本文將針對此，利用一以Bond Graph Method所導得之數學模式以模擬滾子凸輪之動態反應，並在不同操作情形下經由實驗對照來驗證此模擬方式之正確性，以期作為未來設計及觀察時之輔助工具。同時，文中對於力矩補償機構及各式凸輪運動曲線作用於滾子凸輪動態反應之效用進行了分析與觀察。實驗與模擬結果顯示出，力矩補償機構使得滾子凸輪機構之動態精度與穩定性獲得了相當改善。而在模擬過程中亦發現，凸輪運動曲線之部分動態特性對於其系統之振動具有相當的影響。

Roller gear cam (RGC) mechanisms are widely used in modern industries. While operated at high speeds, the indexing precision of these devices will be influenced by their dynamic characteristics. In this study, the Bond Graph Method is employed to construct a mathematical model to simulate the dynamic responses of RGC mechanisms. Meanwhile, associated experiments will be made to verify the effectiveness of this model. The influences of torque compensation mechanisms and different cam motion curves affecting the dynamic response of a RGC mechanism are observed. And the results show that the torque compensation mechanism is effective to the dynamic performance, and high-speed stability of a RGC mechanism. Besides, the simulated results also indicate that the kinematic properties of cam motion curves have certain influences on the residual vibrations of the system.
