这种特有加强肋的薄壁矩形容器其电测应力与美国ASME规范推荐公式计算的应力有较大的偏差。本文对上述矩形容器强度计算方法进行研究推导,并对有关公式进行了修正,建立了该种容器强度计算的新公式。通过两台全尺寸容器在加载情况下的电阻应变测试,表明本文导出的公式的计算应力与电测值是吻合的。 The thin-walled rectangular container with special ribs has a great deviation from the stress measured by the formula recommended by the United States ASME Code. In this paper, the method of calculating the strength of the rectangular container is studied and deduced, and the relevant formula is revised, and a new formula for calculating the strength of the container is established. Through the resistance and strain tests of two full-size containers under load, it is shown that the calculated stress derived from the formulas in this paper is consistent with the electrical measurements.
