载荷偏心对连接件疲劳性能的影响分析

Effect of Eccentric Load on Fatigue Behavior of Riveted structure

采用有限元法与工程梁理论混合分析方法 ,对偏心载荷作用下的连接件结构进行了细节应力分析 ,确立了其疲劳危险部位。并采用应力严重系数法估算了其疲劳寿命。最后应用模拟结构进行了实验研究 。

The detail stresses of the riveted structure are analyzed under the eccentric load by the combination of the Finite Element Method and the Theory of the Engineering Beam first, and then, its fatigue dangerous position is determined. The stress severity factor method is used to calculate the fatigue life of the structure. In the end, the experiment of the simulated structure shows that the result is consistent with the analytic result of the theory.
