基于壓電疊堆的作動器研究
[Abstract]:Piezoelectric actuators have attracted wide attention because of their high precision and precise motion control. In some cases, the traditional actuators will not be able to work normally, such as low temperature, high temperature and electromagnetic interference. Piezoelectric actuators are designed to meet these special environmental requirements. The biped piezoelectric actuator studied in this paper is a kind of non-resonant piezoelectric actuator based on two-stage lever and straight circular flexure hinge structure. It has the characteristics of fast response and large speed. The main research contents are as follows: the application background and characteristics of piezoelectric actuators are introduced, the research status of piezoelectric actuators is summarized, the advantages and disadvantages of resonant and non-resonant piezoelectric actuators are compared, and the piezoelectric actuators designed in this paper are proposed. The basic characteristics of piezoelectric materials are summarized, the application methods of piezoelectric stack are listed, and the output characteristics of piezoelectric stack of NAC2013-H04 are simulated. The structure of the piezoelectric actuator is designed according to the principle of two-stage lever amplification and the structure of straight circular flexure hinge, and its working principle is described. The theory and simulation of the stator amplification ability of piezoelectric actuator are studied, the theoretical value is about 12.8and the simulation value is about 11.284.The dynamic analysis of the piezoelectric actuator is made. Furthermore, the optimization scheme of piezoelectric actuator structure is proposed. The relationship between hinge parameters and stiffness is determined by calculating data and charts, which provides the basis for the optimization of the structure of subsequent piezoelectric actuators. The parameter characteristics of the straight circular flexure hinge are optimized by using ANSYS Workbench to optimize the performance of the stator magnification and the shape of the stator drive foot in the actuator. The material of the piezoelectric actuator is made, and the motion and load capacity of the piezoelectric actuator is studied experimentally. The maximum moving speed of the actuator is 14.286 mm / s, and the stator amplification ability is about 9.146 mm / s, the maximum speed of the actuator is 14.286 mm / s, and the output of the stator is about 9.146 mm / s, the maximum speed of the actuator is 14.286 mm / s. The load capacity is 1.7 N; On the basis of physical assembly and experiments, further optimization and improvement of the related structure of the piezoelectric actuator are proposed. The research contents of piezoelectric actuators are summarized, and the following aspects of the piezoelectric actuator structure are listed, which need to be improved and optimized, and the future research directions are prospected.
