摘　　要：为了验证广珠城际铁路线路平纵断面设计参数的合理性,利用车辆动力学软件ADAMS/Rail建立高速列车和轨道模型,针对广珠城际铁路具有代表性平纵断面设计参数的一段线路,计算了CRH2型动车组在16 km长的线路上运行时的动力响应,并与现行车辆动力学评价标准进行对比。分析结果表明:在现有平纵断面设计参数条件下,CRH2型动车组以200 km/h的速度运行时的所有动力学指标均为优良,行车安全性和舒适性有足够保障,设计参数合理,满足设计及运营要求。For one section of Guangzhou - Zhuhai intercity railway with typical plane and profile section design parameters, a high - speed train and track model was established by employing the vehicle dynamics software ADMS/Rail, and the dynamic responses of EMU CRH2 traveling on a 16 km long track were calculated and compared with the existing vehicle dynamics evaluation standard in order to verify whether the plane and profile section design parameters of Guangzhou - zhuhai intercity railway were reasonable. The results show that under the existing conditions, all the dynamics parameters of EMU CRH2 traveling at the speed of 200 km/h are fine and the driving safety and comfortableness can be guaranteed. Therefore, design parameters are reasonable to meet the requirement of design and operation.
