摘　　要：针对机械原理中平面铰链四杆机构的瞬心线问题,采用作图法和解析法进行研究,清楚地展示了动瞬心线和定瞬心线的作图过程,并以解析的方式给出了两条瞬心线的轨迹方程,同时还解释了动瞬心线沿定瞬心线做无滑动的滚动,有利于学生加深理解,为瞬心线机构的分析设计提供帮助。In view of the centrode problem of planar hinge four--bar linkage in the course of mechanical principle, method of graphic and analytic is applied to clearly show the drawing process of moving centrode and fixed centrode, as well as the trajectory equation of centrode in an analytic mode. The reason of moving centrode rolling without sliding along the fixed centrode is also explained in order to help student understand the theory, and design the centrode mechanism.
