摘　　要：目的针对卷状货物在铁路运输途中常发生横向窜动,造成货物损伤、危及行车安全等问题,基于当前主流运输座架和技术经验,设计一款安全可靠、适用多种车型、可叠放回送、可循环使用、适合多种规格卷状货物、带有横向限位装置的运输座架。方法根据《铁路货物装载加固规则》,制定最不利工况下的卷状货物装载加固方案;依据《钢结构设计标准》及敞车、平车的结构,确定运输座架的结构和材料;通过SolidWorks-Ansys对运输座架进行建模和有限元分析,得到卷钢座架变形及应力的变化情况。结果通过分析可知,运输座架会受到垂向力、纵向力,其最薄弱部分的应力分别为355.14、341.99 MPa,位移变形量分别为0.55、1.069 mm,符合规定;在最不利工况下,横向限位挡件的最大应力为28.89 MPa,最大变形量为0.04 mm,符合规定。结论设计的铁路横向限位运输座架安全可靠,可有效防止货物发生横向窜动;叠装回送,可实现重去重回。该设计填补了现有运输座架对卷状货物无法进行横向刚性加固的空白,对当下卷状货物运输发展具有较大的促进作用。The work aims to design a safe,reliable,widely applicable and recyclable,stacked return,suitable for different specifications of rolled goods and steel frame with lateral stopper seat frame in combination with the current mainstream steel frame and existing technical experience,to solve problems such as the lateral movement of rolled goods that often occurs during railway transportation,causing damage to the goods and endangering the safety of driving.According to the"Railway Cargo Loading and Strengthening Rules",a rolled cargo loading and strengthening scheme under the most unfavorable working conditions was formulated.According to the"Steel Structure Design Standard"and the open car and flat car structure,the structure and material of the steel frame was determined.Through SolidWorks-Ansys modeling and finite element analysis on the steel frame,the deformation and stress changes of the steel frame were obtained.The analysis showed that the steel frame was subject to vertical force and longitudinal force,the stress of the weakest part was 355.14 MPa and 341.99 MPa respectively,and the displacement and deformation were 0.55 mm and 1.069 mm respectively,which met the requirements.Under working conditions,the maximum stress of lateral stopper was 28.89 MPa,and the maximum deformation was 0.04 mm,which met the regulations.The railway horizontal limit steel seat frame is safe and reliable,which can effectively prevent the goods from moving laterally;Stacking and returning can realize repeated removal and return.It fills the gap that the existing steel seat frame cannot carry out lateral rigid reinforcement for rolled goods,which will greatly promote the development of the current roll cargo transportation.
