本文在同时保证扁平绕带式压力容器环向与轴向的静力（包括层间摩擦力）平衡条件均得到满足的前提下，导出了更具一般性的扁平绕带式压力容器的极限压力下限解，给出了预测其内筒是以环向还是以轴向方式爆破的Ａｃ判据。对已有的爆破试验数据验算的结果表明：采用Ａｃ判据对容器内筒爆破方式的预测都是正确的；本文公式计算的爆破压力理论值总是小于实测值，最大误差的绝对值为１４％。 In this paper, under the premise of ensuring that both the circumferential and axial static forces (including the friction between layers) of the flat ribbon-type pressure vessel are satisfied, the ultimate pressure of the more general flat ribbon-type pressure vessel The lower limit solution gives the Ac criterion for predicting whether the inner cylinder is holed in a circular or axial manner. The results of the existing blasting test data show that: Ac criterion is used to predict the blasting mode of the inner tube of the vessel; the theoretical value of the blasting pressure calculated by the formula in this paper is always less than the measured value, and the absolute value of the maximum error is 14 %.
