迄今为止,提升设备结构的设计计算还是建立在静载荷的基础上。动态设计有解析法和数值法两种,它们各有其特点及应用范围。损伤容限设计的出发点是认为构件中均存在着微观或宏观的缺陷,而这方面的工作成果还很少。采用动态设计和损伤容限设计,将大为改善目前提升设备设计计算中所存在的问题。 To date, design calculations to enhance the structure of a plant are still based on static loads. There are two kinds of dynamic design methods and numerical methods, they have their own characteristics and application. The starting point of damage tolerance design is that there are micro or macro defects in the components, and the work in this area is still very little. The use of dynamic design and damage tolerance design will greatly improve the current problems in enhancing the design and calculation of equipment.
