摘要
基于弹性失效设计准则,对柱状储罐进行了二向应力状态的受力分析与计算,得到筒体的轴向应力与周向应力。通过CAE软件建立柱状储罐的有限元模型并进行数值仿真分析,以二向应力状态考虑储罐的受力是可行的。储罐内压为29.6MPa时最大受力处的应力达到材料的屈服强度;筒体削边长度为40mm-80mm时储罐过渡区域受力较大,当筒体削边长度大于100mm时容器所受最大应力趋于稳定。
Based on the elastic failure design criterion, this article makes force analysis and calculation of the cylindrical tank under the biaxial stress state and get the axial stress and circumferential stress of the tank. It is practical to set up the finite element model of the cylindrical tank by using the CAE and calculate the tank force in the biaxial stress state. The results show that the stress at the maximum stress point with the inner pressure of 29.6MPa can reach the yield strength of the material. The transition part bears greater stress when the length of the cutting edge is in the scope from 40mm to 80mm, and the maximum stress of the tank tends to be stable when the length of the cutting edge is longer than 100mm.
