摘要： A connection or weld attachment and method are disclosed for use in connecting a first structural member with a second structural member. An end plate is preferably attached to one end of the first structural member. The end plate and first structural member may then be attached by mechanical fasteners and at least one weld to the second structural member. A railway car having an underframe defined in part by a pair of side sills and a plurality of crossties may be formed with this mechanical connection. The end plate may be attached to a first leg which is in turn attached to the respective crosstie. The first leg preferably increases in width extending from the crosstie to the end plate. The mechanical fasteners are preferably disposed at opposite ends of the weld to minimize possible fatigue cracking and to increase the life of the associated connection.

摘要翻译： 公开了用于将第一结构构件与第二结构构件连接的连接或焊接附件和方法。 端板优选地附接到第一结构构件的一端。 端板和第一结构构件然后可以通过机械紧固件和至少一个焊接附接到第二结构构件。 具有由一对侧梁和多个交叉部分限定的底框的铁路车辆可以用该机械连接形成。 端板可以附接到第一腿部，该第一腿部又附接到相应的横截面。 第一腿优选地从横截面延伸到端板的宽度增加。 机械紧固件优选地设置在焊缝的相对端处，以最小化可能的疲劳开裂并增加相关连接的寿命。
