The invention belongs to the technical field of vehicle engineering, and discloses a vehicle frame, a vehicle frame production method and a vehicle, the vehicle frame comprises a vehicle frame longitudinal beam, the vehicle frame longitudinal beam comprises a web plate and two wing plates, and the thickness of the wing plates is smaller than that of the web plate. The positions of the wing plates are thinned, so that the whole frame longitudinal beam is a thickened plate, the weight of the frame longitudinal beam can be effectively reduced while the requirements of mechanical property, fatigue life and the like of the frame longitudinal beam are met, and the light weight of the whole frame is realized. According to the vehicle frame production method, a control variable method is adopted to analyze the influence of the width of a web plate of the vehicle frame longitudinal beam, the width of a wing plate and the plate thickness of the vehicle frame longitudinal beam on the mechanical property of the vehicle frame longitudinal beam, so that material reduction improvement can be carried out on the part with the minimum influence on the mechanical property of the vehicle frame longitudinal beam, and the vehicle frame longitudinal beam is machined and manufactured according to the analysis result; and the fatigue life of the vehicle frame longitudinal beam is verified, so that the mechanical property and the fatigue life of the produced vehicle frame longitudinal beam meet the requirements, and the light weight of a vehicle frame is reliably realized.
本发明属于车辆工程技术领域,公开一种车架、车架生产方法以及车辆,车架包括车架纵梁,车架纵梁包括腹板和两个翼板,翼板的厚度小于腹板的厚度。对翼板位置进行减薄处理,使车架纵梁整体为变厚板,该车架纵梁在满足力学性能以及疲劳寿命等要求的同时,能有效降低车架纵梁重量,实现整个车架的轻量化。改车架生产方法采用控制变量法分析车架纵梁腹板的宽度、翼板的宽度以及车架纵梁的板厚对车架纵梁力学性能的影响,从而可针对车架纵梁力学性能影响最小的部位进行材料削减的改进,根据分析结果加工制作出车架纵梁,并对该车架纵梁的疲劳寿命进行验证,确保所生产的车架纵梁的力学性能和疲劳寿命满足要求,以可靠实现车架的轻量化。
