基于CAE技术的凸轮轮廓曲线设计

Design of cam contour curve based on CAE technique

针对目前国内企业在间歇运动机构凸轮轮廓曲线设计中所遇到的困难,采用共轭曲线的设计思想和运动模拟仿真的设计思路,并通过案例,介绍了凸轮轮廓曲线的设计方法。通过实体模型验证可知:用此方法得到轮廓曲线的凸轮作为主动件,其从动件的运动状态与初始设定的运动参数相吻合,这一结果给国内企业在解决间歇运动机构凸轮轮廓曲线设计时提供了一种新的思路。

Facing some difficult design which exists in the cam contour curve of indexing motion mechanism against domestic company presently, the conjugate contour curve was viewed as the idea of design and the motion animation was used as the method of design. Using a case, the design method of cam contour curve was introduced. The entity model verifies that, if the contour curve of active cam is designed by this way, the motion Parameters of passive cam which matches the active cam coincides to the parameters ever supposed, the design offers a new way for domestic company to design the contour curve of cam presently.
