The invention provides a side wall structure, a vehicle body and a railway vehicle. The side wall structure is characterized in that a roof side rail is arranged in the length direction of a vehicle, and a door area and a plurality of window areas are formed below the roof side rail; the door upper cross beam assembly is fixedly connected to the top of the door area and connected with the upper edge beam. Wherein the door upper cross beam assembly and the upper edge beam are fixedly connected to form a square-shaped cavity structure, the door upper cross beam assembly comprises a plurality of supporting frames, and each supporting frame is installed in the square-shaped cavity structure and fixedly connected with the inner surface of the upper edge beam. The side wall structure can locally thicken the upper edge beam at the top of the door area by utilizing the door upper cross beam assembly based on mechanical topology analysis, so that the structural strength of the door area is improved; in addition, the door upper cross beam assembly is arranged to be of a square cavity structure, a supporting frame is additionally arranged in the cavity structure, and therefore the structural strength and reliability are further improved in the vehicle width direction, the weight increase of the side wall structure is within a controllable range, and the service life of the side wall structure is prolonged. Therefore, the side wall structure achieves the balance between meeting the strength reliability and meeting the light weight requirement.

    本发明提供一种侧墙结构及车体、轨道车辆。该侧墙结构包括:上边梁沿车长方向设置,上边梁的下方构成门区和若干个窗区;门上横梁组成固接在门区的顶部,并与上边梁相连;其中,门上横梁组成与上边梁固接成口字型腔结构,门上横梁组成包括若干个支撑架,每个支撑架均安装于口字型腔结构中并与上边梁的内表面固接。该侧墙结构能基于力学拓扑分析,利用门上横梁组成对门区顶部的上边梁进行局部增厚,从而提高门区的结构强度;还通过将门上横梁组成设置成口字型腔结构,并在该型腔结构中增设支撑架,从而在车宽方向上进一步提高结构强度和可靠性,并且对于侧墙结构的重量增加处于可控范围内,使得侧墙结构在满足强度可靠性和满足轻量化要求之间达到平衡。
