摘　　要：平面柔性机构自由度的分析可为选择其驱动器提供依据,平面柔性机构由刚性构件、刚性运动副、柔性构件、柔性铰链四个元素组成,不同元素的不同组合得到不同的柔性机构型式,理论上共计15类,工程应用型计11类,在分析单一柔性构件自由度及其影响因素的基础上,基于"伪刚性机构"的思想,提出了两个及两个以上元素组成柔性机构的自由度计算原则,并根据此计算原则对11类工程应用性的平面柔性机构给出了实例机构的自由度计算。The analysis of degree-of-freedom about planar flexible mechanism is foundation of selecting actuator.The planar flexible mechanism is composed of four elements： rigid member,rigid pair, compliant member and flexible hinge.Different combination of different elements can become fifteen types of flexible mechanisms in theory and eleven types in engineering applicability.After analyzing on degree- of-freedom of unit flexible members and inflttential factor,a calctdating principle for Degree-of-freedom of flexible mechanism composed of two or two more elements is given.Based on the Pseudo-gid-body,and experimental analysis of eleven types compliant mechanisms are presented to illustrate the conclusion.
