摘要
应用模糊可靠性设计理论,认为在做保持允许外压差的压力试验时,钢制薄壁圆筒临界失稳强度的模糊可靠度范围为R=99.9999998%~99.9999999%;对薄壁圆筒外压试验的有关问题进行了研究,为压力容器的模糊可靠性设计从理论走向实用提供了参考依据.
The fuzzy reliability range R =99 9999998%~99 9999999% of the critical destabilization strength of steel thin-wall cylinders when conducting pressure tests keeping allowable external pressure difference with analyses using design theory of fuzzy reliability,some problems cocerned with external pressure tests of thin-wall cylinders were studied,and some referable bases from theory to practice were provided of fuzzy reliability design of pressure vessels.
