【摘要】

：

连续卸船机工作时存在工况复杂、载荷多变的特点,疲劳破坏是其钢结构主要失效形式之一.建立整机结构有限元模型,分析作业循环与载荷工况,根据标准规范分析结构疲劳应力;针对回转架结构高应力区,分析不同焊缝形式的疲劳强度,对不达标的焊缝设计不同的结构改进方案,根据改进后的应力改善情况,确定最终方案,提高疲劳寿命.

多丝复合埋弧焊接头冲击性能分析

在大型装备制造业中,多丝复合焊已逐渐进入实际应用阶段.为了探究多丝复合埋弧焊中不同焊丝焊剂组合对埋弧焊接头冲击性能的影响,分别采用不同焊丝焊剂组合,进行多种热+冷丝、热+冷+热丝焊接实验.分析结果表明,8 mm厚钢板多丝复合埋弧焊接头冲击功均满足规范标准(≧27 J);对比其他组合方式,冲击性能最佳的焊剂组合为F1+F3,最佳的焊丝组合为三丝E1+E2+E2.
