Compliant mechanisms are defined as mechanisms that gain some or all of their motion due to the relative flexibility of part or all of their members. Therefore, the design method of compliant mechanism is greatly different from that of traditional rigid-body mechanism and the design methodology for compliant mechanism has not been established systemically till now.

柔顺机构是一种依靠自身的部分或全部具有柔性的构件变形来输出运动或力的机构，它的设计理念及方法与传统的刚性机械设计方法有很大的不同，至今未形成系统完整的设计方法，本文针对这一问题，在国家自然科学基金和国家863计划项目的支持下，提出了轨迹输出平面柔顺机构的一整套设计方法。
