电力机车通过受电弓从接触网上取流是一个动态过程.接触网与受电弓间存在着机械振动及动力学效应.多弓受流是一个多移动振动源的机械振动.这些振动源和接触网一起组成一个复杂的振动系统。本文通过解析及计算机模拟研究.得出一些多弓受流特性的结论

The electric locomotives receive electric current from catenary through pantograph，it is a dynamic process. The mechanical vibration and the dynamics effects exist between the catenary and the pantograph. The multi-pantograph current collection is a kind of mechanical vibration with multi-movable vibration sources ,and these vibration sources together with the catenary compose a complex vibration system. Through analysis and computer simulation researches，several conclusions concerned with the characteristics of the multi-pantograph current collection has been obtained.
