在对受内压旋转壳体的内力分析的基础上,讨论影响失稳的因素,求得椭圆形封头和碟形封头在内压作用时避免失稳的有关参数的范围.“,”Based on the internal force analysis of revolution shells subjected to internal pressure, the factors to influence the buckling of the shells were discussed in this paper. The scopes of the parameters in which the elliptical and dished heads can avoid the buckling under internal pressure, then, were presented.
