Design and Analysis of Micro-displacement Mechanism for Motion Position with Piezo-actuator Based on Triangle Principle |
| |
| Abstract: | A precision micro-displacement mechanism for motion position was designed. The mechanism is driven by piezoelectric multilayer actuators, and output displacement is reduced by the flexure hinges. The principle of mechanism design was carried on. The structure of flexure hinges was designed and the theory analysis and FEA (finite element analysis) was done. The prototype of mechanism was manufactured and the static characteristics were tested. It showed that that the compliant mechanism works the same way as expected. |
