摘　　要：设计了一种基于三角原理的精密柔性定位机构,机构由压电叠堆作为驱动元件,经由柔顺机构输出缩小的位移。首先说明了机构的设计原理,然后设计了柔顺机构的结构,进行了理论计算和有限元分析,最后在试制的样机上进行了静态特性的实验,结果表明该柔顺机构可以实现预期的运动。This paper presents the design of a precision micro-displacement mechanism for motion position. The mechanism is driven by piezoelectric muitilayer actuators, which output displacement is reduced by the flexure hinges. First the principle of mechanism design was carried on, then we designed the structure of flexure hinges and the theory analysis and FEA was done, finally the prototype of mechanism was manufactured and the static characteristics were tested. It showed that the compliant mechanism works the same way as expected.
