直缝焊管成型机接触压力研究

Study on Contact Pressure of Welded Tube with Straight Sew

根据全息光弹实验结果得出的轧辊接触压力的分布规律,进而利用能量方法、轧压理论及厚壁筒理论对开口孔型、闭口孔型的轧辊接触压力进行计算。结果表明理论计算与实测值比较接近,有一定的应用前景。

The article bases on the result of elastic-optic experiment and uses the energy method, roll theory and thick tube theory to calculate the contact pressure in ringent and close section. The result indicates that the theoretical calculation accords with experiment's. It's foreground to be used in practice.
