The aim of this work is to study how well fatigue life predictions, based on Arcan tests results, apply to real joint with a complex geometry, used as a structural component in industrial vehicles. Using a stress-life approach, a master stress-life curve for fatigue was constructed. By utilizing the master curve, fatigue life predictions were made for the joints and compared with the welded assembly. Experimental fatigue tests were performed to verify the predictions. The results agreed with the fatigue life predictions. It was concluded that adhesive bonding is a suitable alternative to welding in terms of longevity.

真实结构构件中胶接接头的疲劳寿命评估

这项工作的目的是研究基于 Arcan 测试结果的疲劳寿命预测如何适用于具有复杂几何形状的实际接头，用作工业车辆的结构部件。使用应力-寿命方法，构建了疲劳的主应力-寿命曲线。利用主曲线，对接头进行疲劳寿命预测，并与焊接组件进行比较。进行了实验疲劳测试以验证预测。结果与疲劳寿命预测一致。得出的结论是，就使用寿命而言，粘合剂粘合是焊接的合适替代方案。
