    對鋼管空拔后出口尺寸變化規(guī)律的計算機模擬研究

    Computerized Simulation of Law of Geometric Variation of Empty-sunk Steel Tube

    • 摘要: 采用計算機有限元仿真手段,進行了鋼管空拔模擬研究,探討了鋼管空拔時壁厚變化現(xiàn)象和縮徑現(xiàn)象的規(guī)律,進而給出了應(yīng)用面廣的計算公式。

       

      Abstract: Simulation research on empty-sunk steel tube was conducted by means of computerized FE (finite element) simulation method, focusing on the law concerning wall thickness variation and diameter reduction of steel tube being empty-sunk. Based on the research, a calculation formula for a rather wide application scope in this regard is deduced.
