Design and analysis of two-dimensional precision positioning platform based on piezoelectric ceramic drive
摘要
Abstract
In order to solve the problems of small displacement magnification,low output stiffness and excessive motion coupling displacement of flexible precision positioning platform,a two-dimensional precision positioning platform based on piezoelectric ceramic drive is proposed.Firstly,the statics modeling for the precision positioning platform was carried out by using the module method,elastic beam theory and flexibility matrix method,and the dynamics modeling was conducted by using the Lagrange equation.Then,the finite element simulation on the displacement magnification,output stiffness,coupling displacement and natural frequency of the precision positioning platform was carried out by ANSYS Workbench software.Finally,the performance parameters of the precision positioning platform were tested by constructing an experimental device,and comparative analyses were conducted with finite element simulation results and theoretical calculation results.The simulation and experimental results verified the accuracy of the statics model and dynamics model of the precision positioning platform,which showed that the designed precision positioning platform had advantages of large displacement magnification,high output stiffness and strong decoupling performance.The research results provide some theoretical guidance for the flexible precision positioning platform to realize large stroke displacement output and excellent decoupling capability.关键词
