摘　　要：文章对现有压电微夹钳结构及位移输出特性进行分析,设计了一种单输入多输出式压电微夹钳。该单输入多输出式压电微夹钳具有结构简单、输出位移可选、振荡小、不易破坏操作对象等优点。文章详细介绍了该微夹钳的结构,并建立起了位移放大倍率模型;利用ANSYS仿真软件对所设计的微夹钳进行分析,仿真结果如下:z方向施加1×10^(-5)mm位移后,钳指指尖顶端可分别产生3.2×10-5mm和5.1×10^(-5)mm位移量;施加间隔为10V的驱动电压,得出其前6阶固有频率,仿真值与解析值具有较高的吻合度,验证了该压电微夹钳结构的可行性与所建数学模型的正确性。The structure and displacement output characteristics of the existing piezoelectric micro clamp were analyzed,and a single input and multiple output piezoelectric micro clamp was designed,which has the advantages of simple structure,optional output displacement,small oscillation,and not easy to damage the operating object.The structure of the micro clamp is introduced in detail,and the displacement magnification model is established.ANSYS simulation software was used to analyze the designed micro-clamp,and the simulation results were as follows:after applying 1×10^(-5) mm displacement in the z direction,the tip of the clamp finger could generate 3.2×10-5 mm and 5.1×10^(-5) mm displacement respectively.The first 6 orders of natural frequencies are obtained by applying the driving voltage with an interval of 10V.The simulation values have a high agreement with the analytical values,which verifies the feasibility of the structure of the piezoelectric micro-clamp and the correctness of the mathematical model.
