摘要
针对飞机上一重要承力连接加强件 ,采用平面四节点等参元与二维受剪钉元组合而成的有限元程序进行了细节应力分析 ,确定了疲劳危险部位。接着 ,在给定的等效载荷谱作用下 ,采用应力严重系数法计算了其疲劳寿命 ,得到了有益的结果。
To analyze the fatigue behavior of joint-strengthened component in aircraft, a series of special finite element method (FEM) programs, in which 4-node isoparametric plane elements and two-dimensional rivet elements are used, are presented to analyze the detail stresses of the riveted component. After calculating the detail stresses of joint-strengthened component and determining its fatigue dangerous position, the stress severity factor method is used to calculate the fatigue life of the component and its fatigue safety life is gained.
