推荐了一种实现轨迹复演的最佳机构。
连杆机构具有复演轨迹的功能并得到广泛应用。
Linkage mechanisms have the function of path generation and have been widely used in industry.
单凸轮连杆组合机构可克服上述缺点，即可以方便地再现预定轨迹并有精确解，但其缺点是难以实现内凹曲线的轨迹复演。
Single CAM linkage mechanism can overcome the shortcomings mentioned above, however the new problem is that the mechanism can not generate the path which has concave curve.
