Design And Simulation Research Of Shock And Vibration Active Control Device Based On Circular Spring Plate

According to the results of analysis and design of former anti-shock and anti-vibration active control devices, a series of circular spring plates are designed and analyzed in this paper. Then the model of electromechanical dynamics is established, and an improved active control device is also designed based on the spring plates.After designing the structures of rotating-blade spring plates and slitting-blade spring plates in using of Pro/E (a 3D mechanical design software), their features are analyzed and compared under different sizes by use of ANSYA (an FEA software); In accordance with design criteria, structure configuration and performance standard, a slitting-blade spring plate is finally adopted, and the whole structure is design and virtually assembled.At last, based on double-sensor control strategy, the numeric simulation of the active control system is researched. Result shows that the system has a good ability to isolate both shock and vibration.The research has the interdisciplinary characteristic that involves machinery, electric, control and measurement. It can control wide-band vibration and violent shock at the same time. The achievements can be widely used in reinforcement of the military computer and its peripherals.
