| 中文摘要: |
| 利用柔顺结构和压电叠层元件的优点，在分析常见柔顺机构的基础上，提出一种压电驱动的柔顺5杆机构。研究该机构各部件的位移输出特性，得到5杆机构顶端的椭圆运动轨迹方程；通过搭建振动位移测试系统，测得该5杆机构顶端的振动位移曲线，验证该柔顺5杆机构可用于精密位移致动器的设计。 |
| 英文摘要: |
| Based on the analysis of common compliant mechanisms, a compliant five bar mechanism driven by piezoelectric actuator is proposed by using the advantages of compliant structures and piezoelectric laminated elements. The displacement output characteristics of each part of the mechanism are studied, and the elliptic motion trajectory equation of the top end of the five bar mechanism is obtained. The vibration displacement curve of the top end of the five bar mechanism is measured by setting up the vibration displacement test system. It is proved that the compliant five bar mechanism can be used in the design of precise displacement actuator. |
