摘要
在战斗机的设计与研制过程中,结构强度始终是一个重点关注的问题。疲劳强度决定了飞机的安全性、耐久性和可靠性等重要指标。全机疲劳试验是验证飞机结构疲劳强度是否满足设计要求的重要手段。本文介绍了国内外全机疲劳试验技术的发展现状,综合分析了我国的全机疲劳试验技术;总结了新型战斗机全机疲劳试验技术成果,包含试验载荷谱、载荷边界模拟、动力系统、数据处理、损伤检测和监测等多个方面,并给出了全机疲劳试验技术的发展规划和建议。该研究可为其他飞机疲劳试验提供重要的技术支撑。
Structural strength is a key concern in fighter's design and development.Fatigue strength of an aircraft determines important indicators such as safety,durability and reliability of the aircraft.Full-aircraft fatigue test is an important method to verify whether the fatigue strength of aircraft structure meets the design requirements.This paper introduces the development history and current situation of the full-aircraft fatigue test technology at home and abroad,comprehensively analyzes the full-aircraft fatigue test technology in our country,and summarizes the important technical achievements of the full-aircraft fatigue test of a new type of fighter,including aspects of test load spectrum,load,boundary simulation,power system,data processing,damage detection,health monitoring,and so on.In this paper,the development plan and suggestions of the whole aircraft fatigue test technology are given.This research can provide important technical support for other aircraft fatigue tests.
