Summary
Pantograph-catenary coupling dynamics and pantograph aerodynamics are the main
factors affecting the current collection quality of a pantograph-catenary system with
the train running at high speed. In order to investigate the dynamic interaction
relationships between the pantograph and the different heights of the catenaries, the
pantograph aerodynamics was combined with the pantograph-catenary coupling
dynamics to analyze the aerodynamic forces of the pantograph with different
working height and the dynamic performance of the pantograph-catenary. The
results show that while the current collection is conducted by the pantograph and
while the catenary with different heights and the aerodynamic forces of the
pantograph are not considered, there is little difference in the dynamic performance
of the pantograph-catenary system. However, the aerodynamic uplift forces of the
pantograph exhibit significant differences for different working heights, so the
current collection quality of the pantograph-catenary is changed dramatically.
Therefore, in order to enable the aerodynamic forces of the pantograph to meet the
requirements of the current collection quality under different working heights, the
optimization of the design of the pantograph aerodynamics and designing the
matched air deflector and controller become particularly important.
