| 摘 要： | 提出一种应用于压电叠堆的微位移放大机构,该机构以压电叠堆为驱动元件,通过基于杠杆原理的柔性铰链二级放大机构,放大压电叠堆的输出位移,在互相垂直的三个自由度方向上通过磁性部件连接,实现三自由度方向上独立的位移输出。同时,通过仿真和试验,对其静态特性和动态特性进行研究。试验测试结果表明:该机构对压电叠堆输出位移的放大倍数达到5倍,三个自由度方向上的位移互相没有影响,并且该机构具有线性良好、高分辨率和高频响应等特点。

| Abstract: | A micro-displacement magnifying mechanism used in piezo-stack is presented.Taking the piezoelectric multilayer actuators as drivers of amplifier,the displacement of piezoelectric multilayer actuator is amplified with the flexure hinge amplifier based on the principles of lever-type amplification.By the magnetic assembly in 3- DOF connecting 3- DOF independent displacements were output.The static and dynamic characteristics are emulated and tested on the prototype;the characteristics of good linearity,high r... |
