近几年来,铁路上矿肥漏斗车的数量显著增加。使用这种车有助于提高装卸作业机械化的水平和劳动生产率。大量的运用经验表明,个别零部件的强度及可靠性指标不完全符合现代化要求,但按照静强度计算和试验结果,承载构件中的应力水平却完全满足了车辆强度计算规范的要求。因此,全苏车辆科学研究院的专用货车分部与列宁格勒铁路运输工程学院合作进行了漏斗车动载荷特点的理论与实验的综合研究。为了评价漏斗车的动载荷,研究了这种
In recent years, the number of mineral hopper trucks on the railway has increased significantly. The use of such vehicles helps to improve the mechanization and labor productivity of loading and unloading operations. A great deal of experience shows that the strength and reliability index of individual components do not fully meet the requirements of modernization. However, according to the static strength calculation and test results, the stress levels in the bearing members completely meet the requirements of the vehicle strength calculation specification. As a result, the specialized truck division of All-China Academy of Vehicle Science and the Leningrad Railway Engineering Institute conducted a comprehensive study of the theoretical and experimental characteristics of the funnel vehicle’s dynamic load. In order to evaluate the dynamic load of the hopper, this kind of study was studied
