高速电动列车受电弓的主动控制

Active Control of Pantographs for High Speed Electric Traction

在高速(可至400km·h^(-1))电动列车的设计中,为了确保动力采集装置正常运行,若采用传统的的被动受电弓,需配置复式链形悬挂系统;而若配置简单链形悬挂系统,则需采用主动控制的受电弓。由于接触网系统是固定设备投资的主要部分,因此,有必要研究受电弓的主动控制,以使列车能运行于现行简单链形悬挂系统从而降低成本。文中受电弓弓头高度与接触力的模拟结果以计算程序FAST(Fahrleitung-Stromabnehmer)在时速直至360km·h^(-1)的情况下得到。与采用传统的被动受电弓所得的结果比较,主动控制受电弓显示了优越性。

Successful current collection for MAGLEV trains or railway trains at velocities up to 400 km ?h-1 requires either complicated catenary systems with conventional pantographs or simple - type catenary systems with active pantographs. Because the catenary system represents the major fixed plant investment an active controlled pantograph with an existing simple- type overhead line is investigated. Simulative results of pantograph shoe height and contact force are produced with the computer program FAST (Fahrleitung -Stroabneher) for velocities up to 360 km h-1. A comparison with the results obtained with a conventional pantograph shows the advantage of an active controlled pantograph.
