飞机起落架抗疲劳制造工艺决策支持系统研究

Study on Decision-making Support System for Anti-fatigue Manufacturing Process of Aircraft Landing Gear

根据飞机起落架的抗疲劳制造工艺和疲劳破坏过程,基于J2EE技术开发框架,本系统建立了构件管理模块、决策处理模块和报告生成模块等功能模块。基于弹塑性力学理论、断裂力学理论、疲劳破坏理论,对飞机起落架的疲劳寿命预测方法进行了研究,研究结果表明以疲劳寿命为目标,为确定飞机起落架抗疲劳制造工艺提供了决策的支持。

According to the manufacturing process of anti - fatigue and fatigue failure process of the aircraft landing gear, based on J2EE technology development framework, this system builds a component management module, establishes a decision - making processing module and a report generation module. Based on the theory of fracture mechanics and fatigue damage, it studies the fatigue life prediction methods of aircraft landing gear. The results show that the goal of fatigue fife provides decision - making support to determine the manufacturing process of anti- fatigue of the aircraft landing gear.
