密封螺栓的模糊许用可靠度与安全系数
Safety factor of seal bolt based on fuzzy allowable reliability
摘要
Abstract
Based on model of static strength-fuzzy and load-stochastic,under different conditions ,the fuzzy allowable reliability of seal bolt static strength was determine ,the relationship between safety factor and fuzzy allowable reliability was explored .The re-searching results show that:1)For seal bolt,in hydraulic pressure tests,gas pressure tests and during normal operation conditions , yield strength fuzzy allowable reliability is equal to 0.983 14,0.998 54 and 0.998 54,respectively;tensile strength fuzzy allowa-ble reliability is equal to 0.999 984,0.999 999 934 and 0.999 999 934,respectively.2) Based on meeting the fuzzy allowable reliability,for seal bolt,yield safety factor should be not less than 1.70 and tensile safety factor should be not less than 2.15.关键词
