胀管率公式在工程中的实际应用与分析

The Actual Application and Analysis of Bulge Tube Rate Formula in Engineering

对现有胀管率公式进行了分析,并根据单管模型试胀试验分析了影响胀管率公式的主要因素,并在胀接概念中明确了胀接的实质,指出了胀接公式中应考虑由于金属轴向流动造成的管壁减薄量ΔS和凸台变化量ΔSW的影响。

This paper analyzes the current bulge tube rate formula, and the main factor which affects the bulge tube rate formula based on the single tube model trying bulge experiment.In bulge connect concept,the paper makes clear the nature of bulge connect. It indicates that in the bulge connect the formula inside should consider the wall reduction measurement Δ S,and the influence of the convex set variety Δ S_W.
