摘　　要：　介绍了锥台式壳体胀球时的结构形式及成球后的参数变化情况,并通过理论分析得出了锥台式结构壳体液压胀形时壳体发生失稳起皱的原因,给出了圆锥台的节数、壳体的半径、壁厚及焊缝强度对壳体变形的影响关系,为采用锥台式结构胀球的壳体结构设计提供了一定的理论依据。Structure of the cone-frustums shell and change of the parameters during hydro-bulging were introduced first. The reason for buckling of cone-frustums shell was analyzed theoretically. Effect of the cone-shells number, radius and thickness of the shell, strength of the welding seam was also given. This provided a theoretical guide for the hydro-bulging with cone-frustums shell.
