    Abstract
  • To study the air-pumping characteristics of brake disc during train operation, the finite element models including vehicle, rail, brake disc and related air flow field were put forward. The air-pumping power consumption of brake disc was calculated, and its effect on traction power was analyzed by using dynamic grid and flow-solid conjugation simulation method.Taking a 8-unit high-speed train composed of 4 motor cars and 4 trailers running at 300 km·h-1 as an example, the air-pumping effect of brake disc was simulated and compared.Simulation result indicates that the air-pumping power consumption of brake disc is in proportion to train running speed.The air-pumping power consumption of each car is about 54-70 kW.The air-pumping torque, independent of installation position of brake disc, is mainly influenced by the rotational velocity of brake disc.The proportion of air-pumping power consumption of brake disc reduces with the increase of train running velocity.When train running velocity increases from 200 km·h-1 to 400 km·h-1, the proportion of air-pumping power consumption reduces from 12% to 8%. Blocking air from the inlets of brake discs is helpful to reduce the influence of air-pumping power consumption.Taking the train running at 300 km·h-1 as an example, when the inlets of brake discs are blocked, the air-pumping power consumption of brake disc reduces from 489 kW to 68 kW, the basic resistance power consumption consumed by air-pumping power consumption reduces from 9.0% to 1.3%, so the method is effective.Obviously, it has greater realistic meanings for the cooling rib structure optimization of brake disc of high-speed train in considering the air-pumping power consumption issue.
