飞机结构中大量的承力构件都是连接件,在交变载荷、腐蚀以及其他因素交互作用下,疲劳源从这些结构处萌生和扩展,从而导致机体结构的疲劳破坏,飞机结构的寿命就取决于这些关键部位。而不同的制孔工艺对连接件又有很大影响。因此,本文从制孔工艺出发,从试验层面和理论计算两方面深入探讨了飞机结构典型连接件之一的螺栓连接件三种不同的制孔工艺对飞机结构疲劳寿命的影响,这对飞机结构的设计和合理的使用与维修有重要的意义。
A large number of load-bearing components in the aircraft structure are connectors, under the interaction of alternating loads, corrosion and other factors, the fatigue sources are sprouted and expanded from these structures, resulting in fatigue damage to the structure of the aircraft and the life of the aircraft structure depends on In these key areas. The different hole making process has a great influence on the connector. Therefore, this article from the hole making process, from the experimental level and the theoretical calculation of two aspects of the aircraft connection in-depth discussion of the typical connector bolts three pieces of the hole forming process on the fatigue life of the aircraft structure, which aircraft structure The design and rational use and maintenance of great significance.
