摘　　要：电力机车运行条件会影响弓网系统滑动摩擦副表面粗糙度,进而影响电力机车的受流质量、运行安全和使用寿命,所以研究电力机车运行条件和弓网系统滑动摩擦副表面粗糙度之间的变化规律有重要意义.采用课题组自行研制的滑动电接触实验机,开展了滑动电接触实验,得到了运行速度、接触电流和接触压力等不同运行条件下滑动摩擦副表面粗糙度参数的变化规律;基于多元线性回归的数学方法,利用实验数据,建立了滑动摩擦副表面粗糙度参数关于运行速度、接触压力和接触电流的数学模型,并通过实验验证了模型的有效性.The operating conditions of electric locomotives will influence the surface roughness of the sliding friction pairs of pantograph catenary system,which in turn influences the current collection quality,operation safety and service life of the electric locomotives.Therefore,it is important to study the change characteristics between the operating conditions of electric locomotives and the surface roughness of the sliding friction pairs of pantograph catenary system.This paper carries out sliding electrical contact experiments based on the self-developed sliding electrical contact experimental machine,and obtains the variation of the surface roughness parameters of the sliding friction pairs under different operating speeds,contact currents and contact pressures.Based on the mathematical method of multiple linear regression,a mathematical model of surface roughness parameters of the sliding friction pairs with respect to the operating speed,contact pressure and contact current is established,and the reliability of the model is verified through experiment.
