摘要
随着疲劳与断裂分析、断裂力学的发展,飞机安全设计理论主要经历了静强度设计、安全寿命设计和损伤容限3个阶段。文中详细论述了飞机安全设计理论发展的历程及主要安全技术,并展望了飞机安全技术的发展趋势。飞机安全设计理论的研究对保证飞行安全,充分发挥装备寿命潜力具有重要的意义。
With the development of fatigue and fracture analysis and fracture mechanics,aircraft safety design theory mainly goes through three stages:static strength design,safe life design and damage tolerance.The development history and main safety technology of aircraft safety design theory are discussed in detail in this paper,and the development trend of aircraft safety technology is prospected.The research of aircraft safety design theory has great significance of ensuring flight safety and utilizing equipment lifespan potential.
