本文给出了储罐和储液仓在其使用期间内破坏概率的计算方法。干扰荷载用随机过程表示,分别使用首次超越破坏准则与疲劳破坏准则对结构进行了动力可靠性分析,文后,附有储液罐水弹性结构的动力可靠性计算实例。可应用于火箭储液仓的随机振动分析及储油罐的随机地震分析。
This paper presents the calculation method for the failure probability of storage tanks and liquid storage tanks during their use. The disturbance load is represented by a random process, and the dynamic reliability of the structure is analyzed using the first-time violation failure criterion and the fatigue failure criterion. An example of the dynamic reliability calculation of the hydraulic elastic structure of the tank is attached. It can be applied to random vibration analysis of rocket tanks and random seismic analysis of storage tanks.
