| Abstract: | A novel micro displacement actuator with very high precision positioning has been developed by use of oppose and positive piezo electric effects of piezo ceramics materials because mechanical micro displacement actuators cannot meet demands of a spacecraft. A set of measuring system has been built, and properties of the actuator are experimented. The experiment result shows good properties of the actuator in precision positioning and vibration suppressing. The theoretical and experimental basis for design and extensive application of a micro displacement actuator in spacecraft is provided. |
