几何画板在机械原理动画演示中的应用

Study on the Application of the Geometer's Sketchpad on Mechanical Principles of Animation Demo

分析了现有文献中几何画板在机械领域的应用现状,应用几何画板实现了四杆机构及其演化机构、渐开线齿廓的形成和凸轮机构的动画演示,并给出了其建模思路和关键点。用几何画板实现机械原理动画演示,其建模过程简单易学,方便高效,动画效果生动、直观。为机构原理的动画演示提供了新的途径,同时扩大了几何画板的应用范围。

This paper analyze the application status of the Geometer＇s Sketchpad in the existing literature in the field of machinery.The formation of four bar mechanism,its evolution mechanism,involute tooth profile,cam mechanism of theanimation,the modeling ideas and key points are carried out by the Geometer＇s Sketchpad.The practice proved that,the modeling process is simple,vivid,intuitive and easy to learn and has highly efficient by the realization of mechanical principle of animation by the Geometer＇s Sketchpad.It provides a new approach to the mechanism principle of animation,and expands the scope of application of the Geometer＇s Sketchpad.
