针对平行分度凸轮机构的特点,提出了基于刚柔耦合理论的动力学建模方法。利用Pro/E,Adams和Ansys软件建立了平行分度凸轮机构的动力学模型,针对不同传动函数对应的凸轮机构进行了仿真和分析。得出结论:变余弦传动函数适合于低速和对传动精度要求不高的场合,盖特曼传动函数和复合传动函数适合于高速、重载、精密传动的场合。复合传动函数是适合高速分度凸轮机构的动力学特性较好的传动函数。
Aiming at the characteristics of parallel indexing cam mechanism, a dynamic modeling method based on rigid-flexible coupling theory is proposed. The dynamic model of parallel indexing cam mechanism is established by Pro / E, Adams and Ansys software. The cam mechanism corresponding to different transmission functions is simulated and analyzed. It is concluded that the variable cosine transmission function is suitable for low speed and less demanding on the transmission. The Guttman transmission function and compound transmission function are suitable for high speed, heavy load and precise transmission. Composite transmission function is suitable for high-speed indexing cam mechanism better dynamic characteristics of the transmission function.
