结合可靠性和概率设计理论，考虑设计参数（压力、径比及材料机械性能）的不确定性，应用不同的强度设计准则，建立相应失效极限状态方程，对高压厚壁圆筒在相同设计工况下可靠性进行计算和对比分析，并对各设计参数在不同强度设计准则下敏感性进行分析。本文结论对高压厚壁圆筒设计具有较为重要的参考价值。 Considering the uncertainty of design parameters (pressure, diameter ratio and material mechanical properties), combined with reliability and probability design theory, the corresponding failure limit state equations are established by applying different strength design criteria. For the same design engineer Under the condition of reliability calculation and comparative analysis, and the design parameters in different strength design criteria sensitivity analysis. The conclusion of this paper is of great importance to the design of high-pressure thick-walled cylinder.
