地震作用下换流变压器阀侧套管的温度场仿真与响应分析

Gaoya dianqi
换流变压器阀侧套管作为电力设备中的关键部件，其安全运行对电力系统的可靠性至关重要。为探究地震作用对换流变压器阀侧套管温度场的影响，文中建立了±800 kV换流变压器及套管体系的精细化有限元仿真分析模型，开展换流变阀侧套管地震响应分析，研究震后阀侧套管表带触指型电连接结构的残余变形与残余应力，基于电连接结构接触电阻计算公式计算接触电阻，分析震后阀侧套管的温度变化。结果表明：触指叶片在地震作用下产生残余变形，接触应力下降，接触电阻上升。由于表带触指的环形结构导致不同位置叶片的变形程度不一致 ...

多因素耦合作用下高强钢焊缝连接疲劳性能研究进展

Jianzhu Gangjiegou Jinzhan
焊接是钢结构广泛采用的连接形式。在提高钢材强度等级后，焊接接头在服役过程中对蚀坑、裂纹等缺陷的敏感度增强，且焊接会劣化钢材成分、组织性能进而导致焊接接头产生初始缺陷。因此，在环境腐蚀、应力集中、超载等因素作用下，钢结构焊缝连接未达到设计服役年限就发生疲劳断裂，造成严重的资源浪费。基于对多因素耦合下高强钢焊缝连接疲劳性能研究现状的总结，介绍了腐蚀疲劳机理及腐蚀预测模型，分析了疲劳设计方法及疲劳寿命评估理论，归纳了焊接残余应力、点蚀坑以及初始裂纹对焊缝连接疲劳性能的影响。结果表明：焊接工艺 ...
