中文摘要:
      结构完整性是飞机结构的重要属性。通常,对结构完整性的描述是一种定性的描述,强调的是对结构完整性的保持,缺乏对结构完整性的定量描述,不利于结构完整性工作全面开展。为此,提出了结构完整性控制的概念;提出了采用结构完整度来度量结构完整性的定量度量方法,并基于结构的完好度、可用度、安全度和存活率评估结构的完整度;提出了以结构完整度最大化为目标优选结构完整性控制方案的结构完整性控制理念,阐明了结构完整性开环控制、协调控制和权衡控制的结构完整性控制的基本内涵,最后基于“建立/评估-维持-验证-恢复/增长-控制”的框架阐述了结构完整性控制的基本任务。提出的飞机结构完整性的度量与控制方法,对其他装备的结构完整性也同样适用。
英文摘要:
      Structural integrity is an important attribute of aircraft structure. Generally, the description of structural integrity is a qualitative description, which emphasizes the maintenance of structural integrity. However, a lack of quantitative description on structural integrity is disadvantageous to the comprehensive development of structural integrity. For this reason, a concept of structural integrity is proposed in this paper. A quantitative measurement is proposed to measure the structural integrity by the structural integrity degree, and the structural integrity degree is evaluated based on the safety degree, intact degree, survival rate and availability degree of the structure. A structural integrity control concept, taking the maximum structural integrity degree as an optimum structural integrity control scheme, is put forward. And the basic connotation of structural integrity control, including the open loop control, the coordination control and the weighing control, is expounded. Finally, the basic task of the structural integrity control is expounded by the framework of the Establish/Assessment Sustainment Validation Recovery/Increment–Control. The measure and control method of aircraft structural integrity proposed in this paper is also applicable to the structural integrity of other equipment.
