The invention discloses a bogie antenna beam structure, a bogie, a railway vehicle and a forming process. The bogie antenna beam structure comprises a first support, a second support, a cross beam pipe and a mounting seat which are made of a fiber resin matrix composite material, first rib faces are arranged in the first support and the second support, the first rib faces divide the first support or the second support into a left-right symmetrical structure, second rib faces are arranged in the installation base, the second rib faces divide the installation base into a left-right symmetrical structure, and one end of the cross beam pipe penetrates through the first rib face of the first support and is fixedly connected with the first rib face of the first support. The other end of the cross beam pipe penetrates through the first rib surface of the second support and is fixedly connected with the first rib surface; the installation base is located in the center of the cross beam pipe, and the cross beam pipe penetrates through the second rib face of the installation base and is fixedly connected with the installation base. The problems that a bogie antenna beam is difficult to manufacture and a welding seam cracks in the using process of a metal structure are solved, meanwhile, the problem of vibration fatigue of the bogie antenna beam structure is solved, and efficient and low-cost manufacturing of a composite material structure is achieved.
本发明公开了一种转向架天线梁结构、转向架、轨道车辆及成型工艺,包括由纤维树脂基复合材料制作而成的第一支座、第二支座、横梁管和安装座;第一支座、第二支座的内部均设置第一筋面,第一筋面将第一支座或第二支座分成左右对称结构,安装座内部设置第二筋面,第二筋面将安装座分成左右对称结构,横梁管的一端穿过第一支座的第一筋面并与其固连,横梁管的另一端穿过第二支座的第一筋面并与其固连;安装座位于横梁管的中心位置,且横梁管穿过安装座的第二筋面并与其固连。本发明解决了转向架天线梁制造困难以及金属结构使用过程中的焊缝开裂问题,同时解决了转向架天线梁结构的振动疲劳问题,实现了复合材料结构的高效低成本制造。
