摘　　要：通过非线性有限元软件ABAQUS建立机翼壁板对接区实体模型,并进行对接区细节分析,同时,根据线性损伤理论估算对接区疲劳危险点在设计载荷谱下的疲劳寿命。The solid model for wing panel butt-joint area is established with the help of the nonlinear finite element software ABAQUS and detailed analysis of the butt-joint area is conducted.In addition,the fatigue life of fatigue hazard points at the butt-joint area in the design loading spectrum is estimated based on the linear damage theory.

关 键 词：应力严重系数 线性累计损伤 疲劳寿命
