Paper Abstract

Intelligent structure was applied widely to aviation and space flight. Intelligent structures are embedded intelligent material in or stick to based body as sensors and activators, which have the functions of sense, identification, judgment controlling and actuation. It introduces the activating control to counteract the original vibration, to reduce the structure vibration. The finite element method, as one of the most efficient numerical value methods, is used to analysis of intelligent structure. The finite equation of intelligent cantileverpiston and its model are established, carry out its finite element analysis and optimum design. The conclusion is that thechief stress on the root of structure is maximal, so it is the optimal position to distribute PZTs. With the outer force increase, more activators are needed to control simultaneously and the reduced vibration effect is very evidently. The activators' shape has great effect on reducing vibration except the position and number.
