According to the railway vehicle side roof structure, the section of a vehicle body of a dome structure does not need to machine the section of a side roof profile, and the strength and rigidity of the section structure of a dome area are improved through the structure; according to the vehicle body section of the flat top structure, side top profiles need to be machined, and part of areas need tobe removed through machining. The structure can be compatible with the structural requirements of a flat top and a dome at the same time, the mold opening cost is reduced, the later machining amountis reduced, the machining difficulty and the machining cost are reduced, and meanwhile the influence on reduction of the section strength of the whole vehicle is considered; according to the invention, the functional structures of the dome and the flat top profile are ingeniously optimized and designed, the dome is not processed and modified, only the flat top area needs to be processed, the processing removal amount is reduced to the minimum, the later process manufacturing difficulty is reduced, the advantages are remarkable, and the innovation point is an important protection point of the invention.

    本发明公开一种轨道车辆边顶结构,圆顶结构车体断面不需要对边顶型材断面进行加工,这样的结构增大了圆顶区域断面结构的强度和刚度;平顶结构的车体断面,需要对边顶型材进行加工,加工去除部分区域。该结构能同时兼容平顶和圆顶的结构要求,降低开模费用,又减少了后期加工量,降低了加工难度及加工成本,同时又考虑了对整车断面强度降低的影响;该发明巧妙对圆顶、平顶型材功能结构进行优化设计,圆顶不做加工改制,只需加工平顶区域,而且加工去除量降至最低,降低后期工艺制造难度,优点显著,该创新点为该发明的重要保护点。
