针对T11型钢轨运输专用车、长大货物平车不能满足50 m长道岔轨的运输需求,根据《铁路货物装载加固规则》的技术条件,选择车辆,设计并布置座架,提出普通平车运输50 m长道岔轨的装载加固方案。根据结构力学的力法原理,建立垂向力学模型,推导出连挂车辆垂向力计算方程组,并编制程序计算车辆承重,分析钢轨挠度,确定普通平车编组连挂方案,并经过试验验证装载方案的可行性。 According to the technical conditions of “Railway Freight Loading and Reinforcing Rules”, vehicles are selected, the frame is designed and arranged according to the special condition of T11 rail transport special vehicles, and the long flat cargo flat trucks can not meet the transportation needs of 50 m long switch rails. Loading and Reinforcement Schemes for 50 m Long Turnout Rails. According to the principle of force mechanics of structure mechanics, the vertical mechanics model is established, the equations for calculating the vertical force of the vehicle are deduced, and the procedure of calculating the bearing capacity of the vehicle is established. The deflection of the rail is analyzed, Feasibility of loading plan.
