Description
Summary:Firstly,based on the compliant mechanisms,theory of machines and mechanisms and spatial mechanisms,a compliant precision positioning platform with six degrees of freedom and driven by piezoelectric ceramic( PZT) actuators is designed. Secondly,a static analysis of the platform is carried out according to the pseudo- rigid- body( PRB) method and virtual work principle,the static stiffness and moving characteristics along six directions are obtained. And a structural optimization is completed through APDL,the maximum stroke along six directions are acquired. Thirdly,a finite element simulation and an experiment in view of the positioning platform are carried out. As a result,the correctness of theoretical model and the rationality of the platform structure are validated by means of the comparison and analysis among the theoretical results,the simulation results and the experimental results.
