FUZZY STRUCTURAL INTEGRITY ANALYSIS FOR TECHNICAL CONDITION OF THERMAL CONTROL SHUTTER MECHANISM ON XX SECONDARY SATELLITE

摘要：

There exits lots of uncertain and fuzzy technical condition during the working process of thermal control shutter mechanism on XX secondary satellite, such as wearing, sealing, deflecting and loosing of parts and components. The paper discuses the evaluation effect and method of technical condition and gives the definition of structural integrity about shutter mechanism. A comprehensive model to fully describe structural integrity of parts using structural error is given, with the characteristic of series connection reliability. So the evaluation index of complex system is simplified based on fuzzy membership function, which provides a fast and easy evaluation method about the whole structural integrity.
