Abstract The current-carrying stability of the pantograph-catenary system directly determines whether the electric locomotives can run steadily and safely under high-speed and heavy-load condition. The contact pressure and sliding speed are two main factors that influence the current-carrying stability. This article simulates the operating state of the pantograph-catenary system by use of the self-made experiment machine, studies the influence of parameters such as speed, pressure on the pantograph-catenary system current stability, and puts forward the evaluation criterion of current stability. The paper theoretically analyzes that the number of the contact spots is the main factors that influence the current stabiliy. The relation model of the contact pressure, the current stability coefficient, the sliding speed and the contact current is established by use of BP neural network . the minimum contact pressure that meets the current stability requirement can be obtained through the model.

Key words： Sliding electric contact current stability current stability coefficient pressure BP neural network
