摘要
目前,化工容器常规设计采用静载荷、高安全系数和规定具体的结构形式,具有很大的不合理性,原因是化工容器大多数受变载荷作用,加之材料本身的缺陷,以及结构的不连续,因此,按疲劳设计更符合工程实际。
Dead load and higher safe coefficient are used in pressure vessel of conventional design.Specific structives are alloted,The design method is shortage in science.Fatigue design is more corresponding with real condition because loads to pressure vessel are change,Material defect exist and structures are discontinue.
