In order to effectively use the vacant space beside the passenger train paths in the train running diagram of mixed passenger and freight lines and draw more freight train paths to improve the carrying capacity , the essay analyzes the reasonable drawing plan for freight train paths beside single passenger train arid two passenger trains respectively on the double tracked section with automatic blocking system according to the principle of minimal additional removal time and on the basis of the calculation method of removal coefficient table 摘要为了在客货共线运行图中有效利用旅客列车运行线两侧的空档,尽可能多地铺画货物列车运行线,以提高区段通过能力,在扣除系数表格计算法的基础上,按照附加扣除时间最少的原则,分析了在双线自动闭塞区段单列旅客列车和2列旅客列车两侧货物列车运行线的合理铺画方案。
In this thesis , according to rules of intensity design for standard gauge freight wagons , the major difference between the standard gauge and the meter - gauge was analyzed . especially , the longitudinal load is researched , and simulation programs are designed , the maximal longitudinal force between couplers is calculated in the situations of traction and brake . and based on the application situations of kunming railway bureau , the specification for the intensity design and accreditation test about the meter - gauge freight car is established 本论文根据准轨货车强度设计标准,对准轨、米轨差异较大部分,特别针对其纵向载荷进行了研究计算,编制了计算机仿真程序,求解了米轨货物列车在牵引、制动等工况下车钩间的最大纵向作用力,并结合昆明铁路局米轨线路的实际运用情况,制定出了米轨货车强度设计与试验鉴定准则。
