| 摘 要： | 点焊是铁路不锈钢车体广泛采用的焊接技术,用于连接金属薄板结构或帽型结构。一个典型不锈钢车体包含约三万个点焊,在车体结构分析中详细创建每个点焊的有限元模型是不现实的,需要用简单的模型代替。文章介绍了薄板点焊结构有限元模型的七种创建方法,从动力学角度分析了试样各种有限元模型的振动特性,并与试验结果进行对比,旨在得出一种适合不锈钢点焊车体结构振动分析的点焊模型。

| Abstract: | Spot welding is a widely employed technique to join sheet metals and cap structures for the railway stainless steel car body.A typical car body contains about thirty thousands spot welds,it is not practical in the car body structure analysis to model each and every spot-welded joint in detail,and simple models need to be used instead.In order to educe a compatible spot weld model for the stainless steel car body structural dynamics analysis,this paper presents seven spot weld models,the sample vibration cha... |
