The invention relates to a railway vehicle composite material built-in profile framework and a railway vehicle, and belongs to the technical field of railway vehicles. The framework comprises cross beams, longitudinal beams and hanging pieces; the cross beam is perpendicular to the length direction and comprises a plurality of inner cavities arranged horizontally, waist lines extending in the length direction of the cross beam are arranged in the inner cavities in the two ends, and the waist lines protrude towards the inner cavities on the side walls of the inner cavities. The longitudinal beams are perpendicular to the length direction, and waist lines extending in the length direction of the longitudinal beams are arranged in the inner cavities. The inner surface of the inner cavity of the cross beam is as high as the outer surface of the longitudinal beam; the hanging piece is hung in the inner cavity provided with the waist line, and the hanging piece is limited by the raised waist line; the cross beams and the longitudinal beams are made of fiber reinforced resin composite materials, and the waist line position is filled with composite fiber one-way fabric. The inner cavities are formed in the cross beams and the longitudinal beams, the inner surfaces and the outer surfaces make contact with each other when the cross beams and the longitudinal beams are connected in an inserted mode due to the height arrangement of the cross beams and the longitudinal beams, and the connection strength of the contact positions is improved.
本发明涉及一种轨道车辆复合材料内装型材骨架及轨道车辆,属于轨道车辆技术领域。骨架包括:横梁、纵梁和吊挂件;横梁在垂直于长度方向上,包括多个水平排列的内腔,两端的内腔中设置有沿横梁长度方向延伸的腰线,腰线在内腔侧壁上向内腔中凸起;纵梁在垂直于长度方向上,内腔中设置有沿纵梁长度方向延伸的腰线;横梁的内腔内表面的高度与纵梁的外表面高度相同;吊挂件吊挂于设置有腰线的内腔中,且吊挂件受凸起的腰线限位;横梁和纵梁为纤维增强树脂复合材料,腰线位置填充有复合纤维单向织物。本发明优化统型型材断面和种类优化获得,横梁与纵梁中设置内腔,两者的高度设置使得两者互相插接时内外表面互相接触,提高了接触位置的连接强度。
