空拔圆管壁厚变化的上界解分析

    UPPER LIMIT ANALYSIS OF WALL THICKNESS VARIATIONS IN PIPE SINKING DRAWING

    • 摘要: 利用连续速度场分析了圆管空拔过程,建立了空拔壁厚变化量计算式。经验证,该式计算的空拔壁厚变化量与实际值基本一致,可用于工程计算。

       

      Abstract: Pipe sinking drawing is analysed using continuous speed field and the equations of wall thickness variations in sinking drawing established. By test, the variations calculated with the equations are in conformity with the actual values and can be used in engineering calculation.
