【Abstract】 The concept, theorem, analysis method, research status and main research content of the intelligent structure which is one of the research hotspot are introduced detailedly in this paper. The key relevant technologies are proposed in the design of structures of spacecraft from the point of view of technical application. Finally, an example of a new low voltage piezoelectric active member with integrated load cell and displacement sensor is described. This active member is intended for micron level vibration and structure shape control of the precision segmented reflector test-bed.更多还原
