摘要
飞机结构设计思想随着航空技术的发展而不断进步,经历了从静强度、动强度、疲劳强度到断裂强度的变化过程,耐久性/损伤容限设计是当前飞机结构设计规范的核心方法。本文归纳了飞机结构设计思想的发展历程,重点讨论了耐久性/损伤容限设计的基本思想、基本理论和基本方法,有助于深入理解该设计思想的本质。
With the development of aeronautical technologies, aircraft structure design concept has made continues progress, and undergoes an evolutive course from static, dynamic, and fatigue to fracture strength. And then, durability and damage tolerance design become the key method of current aircraft structure design criterion. The paper summarizes the developing history of design concept, emphatically discusses the basic concept, theory and method of the durability and damage tolerance design. These will be useful to understand an essence of the design concept.
