摘　　要：连杆轨迹作为现代机构研究的一个重要对象,在对机构性能要求不断提高的背景下,研究弹性变形引起的连杆轨迹误差有着十分重要的意义。详细分析了平面五杆混合驱动机构刚性体和变形体两种情况下的连杆轨迹,得出了弹性变形对机构的连杆轨迹的影响比较明显,不能忽略。The linkage trajectory is an important study object of modern mechanism,with the modern mechanism performance requirements continually improving, study the elastic deformation due to linkage trajectory error has a very important significance. The linkage trajectory on the five--bar hy- brid driven mechanism of the plane rigid body and deformable body are analyzed. The influence of elastic deformation on the mechanism linkage trajectory is obvious and cannot be ignored.
