摘要

凸耳是飞机结构中连接部件、传递载荷和运动的关键环节。由于它们的机械功能，它们的故障将导致严重的后果。为了保证结构的安全，应充分考虑和量化影响结构疲劳性能的因素。本文对凸耳与负载销之间不可避免的摩擦和间隙的影响进行了量化。采用经典的局部应力法和修正的临界距离理论对直耳和斜耳的疲劳寿命进行了预测。在预测和广泛的实验之间取得了令人满意的相关性。

Fatigue Life of Pin-Loaded Lugs: Friction and Clearance Effects

Lugs serve as crucial linkages in aircraft structures to connect components and transmit loads and motions. Because of their mechanical functions, their failure would lead to severe consequences. To ensure structural safety, factors that could affect the fatigue performance should be well considered and quantified. In this paper, the effects of the inevitable friction and clearance between the lug and load pin are quantified. The fatigue lives of straight and oblique lugs are predicted by using the classical local stress approach and a modified theory of critical distances. Satisfactory correlations between the predictions and extensive experiments are achieved.
