中文摘要：

采用数值计算方法对2车编组的CRH1型高速列车以不同速度通过车站和于车站内交会进行了模拟，研究了DSA型受电弓升力变化及运行状态（闭口和开口）和屏蔽门对受电弓升力的影响。研究表明，列车进、出车站过程受电弓升力波动显著。单车以闭口和开口状态下过车站时，均为弓头和上框架升力变化最大，受电弓运行状态不改变弓头升力变化幅值与车速幂次方呈线性关系，且开口状态下弓头升力变化大于闭口状态，屏蔽门对受电弓升力影响有限。列车在站内交会时，受电弓运行状态显著改变了受电弓各部件升力变化及其随车速变化规律，屏蔽门对交会工况的影响比单车工况显著；车站内交会位置对受电弓升力变化基本无影响；不等速交会对受电弓变化影响明显。

英文摘要：

By using numerical calculation method, 2-ear high-speed train going through the station or intersecting at the station at the different speed was simulated. The bow lift change, influence of pantograph state and harrier door on pantograph lift change was researched. Results indicate that, during the train coming into the platform or going out of it, the fluctuation of pantograph lift is significant. When the train going through the platform, lift change of pantograph bow and upper frame is the biggest. There is a linear relationship between pantograph how and the power of speed, and the law is not changed by pantograph state. Lift change of pantograph bow in the state of adverse pantograph is greater than it in the state of favorable pantograph, and influence of barrier door on the pantograph lift change is limited. When two trains are passing each other through the platform, distribution of lift change of pantograph components and law of lift change with train speed are changed signifi- cantly by pantograph state. Influence of barrier door on the pantograph lift change is more obvious than one of the train going through platform. The meeting position in the station has no effect on the lift change of pantograph. Lift change of pantograph is affected obviously by nomuniformity of train passing.
