2、动态通过R300m曲线时的动力学性能，并与实测试验结果进行对比分为机车车辆动力肇析。结果太明：动乍动力学性能同时受轨道局部不平顺和随机不平顺的影响，随机不平顺的影响占60％；实际线路缓圆点位置随机不平顺比嘲曲线h随机不平顺大；实际中R300m曲线横向不平顺在缓圆点处接近较差线路横向不平顺，flfI线f：略大于AAR5级线路横向不平顺；垂向不平顺在缓圆点处接近AAR5级线路垂向不平顺，『f{1线I接近AAR6级垂向不平顺；脱轨系数实测最大值约为较差线路最大值的1．2倍，平均最大值约为较差线路最大值的1

3、．I倍。建议在今后的小半径曲线仿真分析中考虑不平顺的异。关键词：1人】燃动年组；动J学性能；动态通过；小半径曲线；仿真分析；实测试验中图分类号：U266．11：TP391．9文献标识码：A文章编号：1000—128X(2014)02—0035—03ComparisonandAnalysisofSimulationandMeasuredResultsonA1A·A1AMotorVehicleDynamicalNegotiatingSmallRadiusCurveDynamicPerformanceLI
