Satellite Disturbance And Vibration Characteristic Simulation Technology Research

In this paper, the micro displacement angle vibration table is studied,the angular vibration under voltage control along ?x deflection motion, the movable table along the ?z deflection, the movement of the whole compound to form a two degree of freedom.Micro displacement angle vibration table of the guide with a flexible hinge, related formulas of the design of flexure hinge are derived, using MATLAB programming to simulate the function curve of the flexible hinge, according to the function curve, the experiment is repeated. After the design is finished, using ANSYS Workbench static analysis?dynamic analysis and fatigue life analysis.Design a set of power supply with the selected piezoelectric ceramic, understanding of the characteristics and principle of the piezoelectric ceramic driver, a set of DC amplifier driving circuit is designed. Finally, a series of performance tests of the driving circuit are carried out.Micro displacement angle vibration table system controlled by PID closed loop control system, the dynamic response performance of the system is greatly improved by the PID control algorithm based on the Preisach model.
