摘　　要：针对大秦、瓦日铁路的通用敞车和专用敞车编组重载列车的试验结果,对比分析编组质量、循环制动性能、紧急制动距离、列车纵向力性能等参数。结果表明,在相同站线条件下,通用敞车编组质量小于专用敞车,其循环制动性能、紧急制动距离、列车纵向力等参数都能满足重载列车要求;通用敞车可作为重载列车的编组车辆,应用于单元万吨和组合万吨重载列车中。According to test results of heavy-haul trains consisting of general and dedicated gondola cars along Datong-Qinhuangdao Railway and Watang-Rizhao Railway,this paper comparatively analyzes the parameters,such as traction mass,cycle braking performance,emergency braking distance and train performance in longitudinal force.Analysis results show that under the same conditions of the station and tracks,the train consisting of general gondolas is lighter than train consisting of dedicated gondolas and its performance can meet the requirements for train parameters,such as cycle braking performance,emergency braking distance and longitudinal force;It is concluded that the general gondola cars can be applied to 10000 t unit and 10000 t combined heavy-haul trains.
