摘　　要：对等边双圆锥台进行了液压胀形试验，研究了该种壳体的起皱情况。结果表明，在胀形过程中，由于压应力的存在，壳体在赤道环焊缝处产生径向皱纹，增大内压力难以消除该种皱纹。Buckling of an equilateral double-cone-frustums shell is studied when it is bulged. The result shows that the shell will buckle at the equatorial ring weld and produce longitudinal buckles because that compression stress exists during bulging,and it is difficult to eliminate the longitudinal buckles by increasing the inside pressure of the shell.
