软介质胀管中胀接压力的确定

Determination of the Expanding Pressure in Soft Medium Expansion of Tubes

本文以弹塑性理论为基础，分析了在软介质胀管过程中管子与管板的受力和变形情况，给出了胀接压力的选取范围及计算方法和残余接触压力的计算方法，并用实例进行了验证。

In this paper, the strain-stress relationslnp between tubes and tubesheet was analysed with elasticity-plasticity theory. A procedure was proposed to determine the expanding pressure and residual contact pressure. And a pratical examples was used to verify the correction of the method.
