The invention discloses a railway flatcar body and a longitudinal beam of a railway flatcar, the longitudinal beam comprises an upper beam body and a lower beam body, the lower beam body is located below the upper beam body and is installed in the middle area of the upper beam body in the longitudinal direction through a connecting piece; the lower beam body comprises two end beam modules and a middle beam module, the two end beam modules are both installed on the two longitudinal sides of the middle beam module through connecting pieces, the middle beam module is an equal-height beam body, at least part of each end beam module in the longitudinal direction is a variable-height beam body, and the variable-height beam body is an equal-height beam body. And in the longitudinal direction, the height of the variable-height beam body is gradually increased in the direction close to the middle beam module. Welding of the longitudinal beam is less, the green production level is high, reasonable distribution of strength of different areas of the longitudinal beam is facilitated, and then the weight can be reduced.

    本发明公开一种铁路平车的车体及铁路平车的纵梁,其中,上述纵梁包括上部梁体和下部梁体,所述下部梁体位于所述上部梁体的下方,并通过连接件安装于所述上部梁体在纵向上的中间区域;所述下部梁体包括两个端部梁模块和一个中部梁模块,两所述端部梁模块均通过连接件安装于所述中部梁模块的纵向两侧,所述中部梁模块为等高梁体,所述端部梁模块在纵向上的至少局部为变高梁体,在纵向上沿靠近所述中部梁模块的方向上,所述变高梁体的高度逐渐增大。上述纵梁的焊接较少,绿色化生产水平较高,且有利于纵梁不同区域处强度的合理分配,进而可以减轻重量。
