摘要
应用可靠性设计方法,在最苛刻的气压与液压试验条件下,对球形容器初始静强度的可靠度范围进行了定量分析;结果表明:①初始屈服强度在气压试验时的可靠度为Rs1=94.630%~98.809%,在液压试验时为Rs2=78.81%~86.65%;②初始爆破强度在气压试验时的可靠度为Rb1=99.801 2%~99.999 998 93%,在液压试验时为Rb2=98.030%~99.999 570 6%.
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. The result shows that: The reliability range of virgin yield strength is equal to Rs1 = 94.630%98. 809% under pneumatic test, and Rs2 = 78.81% -86.65 % under hydraulic test; The reliability range of virgin explosion strength is equal to Rb1=99.801 2 % - 99. 999 998 93 % under pneumatic test and Rb2=98. 030 % -99. 999 570 6 % under hydraulic test.
