摘　　要：基于长径比相同的软态TP2内光壁铜管与内螺纹铜管的爆破压力实测数据无明显差异分析,讨论了长径比对铜管爆破压力的影响,建立了计算软态TP2短铜管爆破压力的经验公式,得到了区分软态TP2长短铜管的临界长径比。Based on experimental investigations,there was no significant difference between the burst pressure measured data of copper pipe and inner thread copper pipe under same slenderness ratio.In this research the effect of slenderness ratio on the burst pressure of copper tube was discussed,the empirical formula for calculating burst pressure of soft state TP2 short copper tube was established,and the critical slenderness ratio for differentiation the long or short of soft state TP2 copper pipe was obtained.

关 键 词：软态TP2 长短铜管 爆破压力 经验公式 临界长径比
