随着航空航天技术的发展,飞机结构设计的理论与思想也不断更新,从静强度、动强度、疲劳强度及断裂强度的进化,而损伤容限/耐久性分析也已成为目前飞机结构设计的重要规范。本文将从飞机结构设计的发展历史说起,详细介绍飞机损伤容限与耐久性分析的设计思想、理论和基本方法,为飞机结构设计提供理论基础。 With the development of aerospace technology, the theory and thought of aircraft structure design are continuously updated. From the evolution of static strength, dynamic strength, fatigue strength and fracture strength, the damage tolerance / durability analysis has become the current design of aircraft structure Important specifications. Starting with the history of the development of aircraft structure design, this paper introduces the design concepts, theories and basic methods of aircraft damage tolerance and durability analysis in detail, which provides the theoretical basis for aircraft structure design.
