Abstract

The invention provides a pantograph dynamic operation performance control method and device. The pantograph dynamic operation performance control method comprises the steps that a pantograph line aerodynamic performance test is performed so that aerodynamic performance parameters of a pantograph in different open directions and speed levels are generated; a pantograph and catenary current collection performance test is performed so that the pantograph and catenary current collection performance parameters of the pantograph in different operation lines and different open directions and speed levels are generated; a catenary contact force trend regression curve under different speed levels and different open directions is drawn by utilizing a quadratic polynomial curve regression method according to the pantograph and catenary current collection performance parameters and the aerodynamic data; and dynamic operation performance of the pantograph is controlled according to the catenary contact force trend regression curve. With application of the pantograph dynamic operation performance control method and device, the pantograph dynamic operation performance parameters of the pantograph can be accurately controlled so that indirect contact force of the pantograph and the catenary can be accurately controlled, and great current collection of the catenary and the pantograph can be guaranteed.

Description

technical field

[0001] The present invention relates to pantograph control technology, in particular to a pantograph dynamic operation performance control method and device. Background technique

[0002] The pantograph is an important equipment for the operation of the EMU and the electric locomotive, and its good match with the catenary is the guarantee for the normal flow of the EMU and the electric locomotive. The performance of the pantograph in multiple processes is tested, and the pantograph-net matching performance of the pantograph can be completed to accurately control the dynamic operation performance parameters of the pantograph. At present, there is no method to realize the above functions, and it is impossible to achieve EMUs and electric locomotives receive normal flow. SUMMARY OF THE INVENTION

[0003] The invention provides a pantograph dynamic operation performance control method and device, so as to ensure that the pantograph dynamic operation performanc...
