Digital Simulation Study of the Pantograph-Catenary

The research of pantograph-catenary digitalization is an important method for the design of pantograph-catenary scheme of high-speed train, and it is an important way to break through the key theoretical foundation and technology of pantograph-catenary, and also an important process to adapt to the research and development of pantograph-catenary of higher-speed train, and the simulation of pantograph-catenary flow performance based on digitalization is the requirement of higher-speed train for the stability and safety of pantograph-catenary flow performance. In this paper, we mainly use the independently derived three-mass block bow network coupling model equations, and use MATLAB to build the simulation model of the pantograph and catenary, and simulate the contact force fluctuation characteristics of the pantograph and catenary at the train operating speeds of 100 km/h, 200 km/h, and 300 km/h, and obtain the contact force fluctuation characteristics of the pantograph and the contact network when the train operating speeds are 100 km/h, 200 km/h, and 300 km/h respectively. The change characteristics of the contact force of the pantograph-catenary with time at 300 km/h are obtained, and it is found that the average value of the contact pressure between the pantograph and the catenary increases gradually and the fluctuation is more and more intense with the increasing of the running speed of the train. Therefore, the digital simulation of the pantograph-catenary performance can reduce the cost of research and development, reduce the cycle of research and development, and improve the efficiency of research and development.
