小口径管换热设备的电爆炸胀接变形能的计算

A Calculation of the Deformation Energy of the Electrosparking Expansion Joint of the Heat Exchange Equipment With Small-Caliber Tubes

介绍了利用电阻丝(箔)瞬间爆炸产生的超高压来完成胀接的一种新型爆炸胀接方法。利用图算法从理论上计算了小口径管(小于14mm)的胀接变形能量,并对这种电爆炸胀接技术进行了探讨,给出了胀接变形能的计算公式。

A new explosive expansion joint method was presented of using superhigh pressure generated with the transient explosion of resistance wire （ foil ） to complete expansion joint. The deformation energy of the expansion joint of small-caliber tubes （below 14mm） was calculated using nomography in theory, the electrosparking expanded technology was discussed, a formula was given for the deformation energy of expansion joint.
