1) Minimum reliability range
2) Reliability range
By using reliability design method, the reliability range of virgin static strength of spherical vessel was quantitatively analyzed under the most severe pneumatic and hydraulic test conditions.
3) minimal reliability
By using reliability design methods, minimal reliability of virgin static strength of steel thin wall cylinder during pressure test is quantitative analyzed.
4) initial reability scope
5) Fuzzy Reliability Range
In this article,the cylinder testing pressure and safe factor is researched from controlling its fuzzy reliability range of bursting strength of ultrahigh pressure cylinder during pressure test and normal operation based on the reliability design theory and methods of random-fuzzy probability model.
The relationship between external testing pressure coefficient and the two factors, the buckling safety factor and the fuzzy reliability range was quantitative analyzed based on the random-fuzzy probability model.
6) Minimal Virgin Reliability
