摘要

本文發展含碰撞偵測的一般性動力模擬軟體，將可用來分析在同一運動平面上，具有直接接觸傳動件並且有發生衝擊碰撞現象之機構的運動。本研究所提出之碰撞偵測方法能精確、有效率且穩健地偵測任何共平而運動之桿件的相互碰撞模式，並根據其模式進行機構運動的動力模擬。其次，再利用兩種常用來分析接觸和衝擊的現有模型進行探討與評估，並建議以加入接觸拘束的方式處理非衝擊性之接觸問題。最後再以應用例說明此動力模擬系統之相關功能。

A general-purpose simulator is implemented in this study for analyzing the motion of mechanisms with planar direct contact members; i.e., contacting bodies lie in a plane. This is because the proposed collision detection method can only deal with planar link profiles currently. However, it is accurate, efficient, and robust. Two different contact models, that are available for dynamic analysis of rigid bodies with contact and impact, are studied and evaluated. Then, a contact constraint is suggested for dealing with those non-impulsive contacts when using discrete contact dynamics models. Case studies are also presented for illustrating the functionalities of the simulator.
