Problems solved by technology

However, since the high-speed pantograph is a mechanical system with a complex structure, its performance is affected by multiple disciplines, such as operating accuracy, structural strength, dynamic characteristics, control analysis, etc., and the current research only focuses on a certain influencing factor. analyses, the interaction between these factors has rarely been explored to influence the pantograph

Description

technical field [0001] The invention relates to a high-speed railway pantograph-catenary system optimization design method, in particular to a high-speed pantograph structural parameter optimization method. Background technique [0002] A pantograph is installed on an electric locomotive or an electric vehicle. It is an electrical device that obtains current from one or more contact wires or receiving rails; it generally consists of four parts: a base, a transmission mechanism, a frame and a bow head. Composition, in which the bow head is installed on the frame, the base supports the frame and is fixed on the roof through insulators, and the transmission mechanism is connected with the frame to control the process of raising and lowering the pantograph. High-speed trains obtain electric energy from the catenary through the pantograph. The stable contact between the pantograph and the catenary is an important condition for the train to obtain good current flow. Once the panto...
