| 摘 要： | 通过应力测定和爆破试验，对厚壁螺旋管进行强度研究。结果表明：光管成型加工成螺旋管后，虽然爆破强度不会下降，但其应力分布变得复杂，既存在拉应力又存在压应力，且方向也不一致。最大应力发生在螺旋管的根部，为拉应力。与光管比，螺旋管中的应力分布明显劣化，最大应力是成型前的8倍多。最后指出螺旋管的允许工作压力应综合考虑爆破强度、应力状态和使用环境等因素确定。

| Abstract: | The strength of spiral tube with thick wall was investigated through stress determination and bursting test. The results indicated that when a straight rube is formed into a spiral tube, its stress distribution becomes complicated, and both tensile stress and pressure stress exist and their directions are not in the same direction though the bursting strength will not decrease. Comparing with a straight tube, the stress distribution becomes worse obviously in the spiral tube and its maximum stress at the root becomes more than 8 times that of the straight tube . It was concluded that the allowed working pressure of the spiral tube should be determined through considering bursting strength, stress states and process conditions comprehensively. |
