摘　　要：针对介于具有集中柔度和具有分布柔度之间的全柔性机构,提出了第三类具有不完全分布柔度的全柔性机构的概念,并定义了其特征尺寸比值,根据这类全柔性机构的特点,提出在用伪刚体模型分析具有集中柔度全柔性机构的基础上,考虑构件弹性变形的分析方法.实例计算结果表明了该方法的有效性.A new concept,incompletion distributed complete compliant mechanism,was proposed.The compliance of incompletion distributed complete compliant mechanism,the third complete compliant mechanism,is between those of lumped compliant mechanism and distributed complete compliant mechanisms.In order to classify the complete compliant mechanism,a new concept,character dimension ratio,was also given.According the characteristic of the third complete compliant mechanism,the deflection of link was taken into account when complete compliant mechanism was analyzed with pseudo-rigid-body model.Finally,the calculation of an example was given and the result indicates that the method is validity.
