摘要
Abstract
Non-fold conical shell under external pressure not only needs to satisfy self-strength and stabili-ty requirements,but also needs to provide strengthen design and stability checking at big and little-endian between cylinder and conical shell.In this paper,strengthen design principle was theoretical discussed simply based on the first theory of ASME Ⅷ-1 .In addition,it comes to the conclusions that:stability sta-bility increases at first then decreases with half cone angle increases,stability improve significantly with conical thickness increases,radius ratios has no significantly influence on stability,which based on the fi-nite element method.Further more,stability will be improved significantly when stiffening ring located at the position of the maximum circumferential compressive stress.关键词
