组合式登机桥高强度螺栓群的强度计算

Strength Calculation of the Combined Aerobridge of High Strength Bolts

摘要: 组合式登机桥采用全新的设计概念，标准模块可独立制造和运输，在现场快速装配。由于结构设计要求以及为了外形美观，组合式登机桥接合部高强度螺栓群中螺栓直径大小不一，本文针对不同设计方案，研究通道接合部高强度螺栓群强度计算方法。在登机桥联接与接头的抗疲劳设计中，得到高强度螺栓疲劳强度条件。

Abstract: The combined aerobridges are designed by a new concept with independent manufactured and transported standard modules which can be assembled rapidly. Due to the structural designed requirements as well as their appear-ance, the bolts in high-strength bolt group of the combined part have varied diameters. This paper studies computing method of high-strength bolt group in combined part according to the different designing schemes. We get fatigue strength condition of high-strength bolts in the fatigue design of aerobridge connections and joints.
