The invention discloses a molding method of an arc floor of a railway vehicle. The method comprises the steps of selecting a plurality of core materials with the proper thickness and width according to the thickness and the lengths of a linear section and an arc section of the floor in the vehicle; splicing the core materials in the same direction in sequence according to the lengths of the linearsection and the arc section of the floor to form a core material splicing slab; putting the core material splicing slab into a mold formed pursuant to the cooperation of the length of the linear section and the arc length and radius of the arc section of the floor in the vehicle for molding. The arc floor of the railway vehicle comprises an upper panel, a lower panel and a middle core material layer, wherein the middle core material layer is formed by splicing a plurality of the core materials with different widths, and a tackiness agent is adopted for achieving adhesion between the upper panel, the lower panel and the middle core material layer and between the core materials. According to the molding method, the feeding width of the core materials is flexibly adjusted according to the length of the linear section, the radius of the arc section in the vehicle body structure and other parameters, and after the core materials with different widths are spliced, laying of the arc floors of different vehicle body structures can be met.
一种轨道车辆弧形地板成型方法,根据车内地板厚度以及直线段和弧线段长度,选取若干具有合适厚度以及宽度的芯材;将所述的芯材根据直线段和地板弧线段长度依次同向拼接,形成芯材拼接平板;将所述芯材拼接平板放置于根据车内地板直线段长度以及弧线段弧长、半径配合的模具中成型。轨道车辆弧形地板包括上面板、下面板以及中间芯材层,所述中间芯材层由若干宽度不同的芯材拼接形成,所述上面板、下面板与中间芯材层之间以及所述芯材之间均通过胶粘剂粘接。本发明根据车体结构中的直线段部分长度以及弧线段部分的半径等结构,灵活地调整芯材下料宽度,将不同宽度的芯材拼接后即可满足不同车体结构的弧形地板铺设。
