Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0026] In order to overcome the relatively simple structure of the traditional drag increasing plate, which is only driven by a simple hydraulic mechanism to realize the problem of increasing the resistance of the plate, this application proposes a method and structure for increasing resistance and reducing load of high-speed trains using supercritical wing technology. It can realize effective resistance increase and deceleration and load reduction and speed increase when the train is running.

[0027] Such as figure 1 with figure 2 As shown, the high-speed train resistance increase and load reduction method provided by the application draws lessons from the supercritical wing technology in the design of t...

Abstract

The invention provides a resistance increasing and load shedding method for a high-speed train, which comprises the following steps of: constructing a resistance increasing plate with a wing-shaped section, and arranging a high lift device capable of rotating relative to the resistance increasing plate at the rear edge of the resistance increasing plate; a resistance increasing plate with a high lift device is installed on the top of the high-speed train through a transmission mechanism; when the resistance of the high-speed train needs to be increased, the resistance increasing plate is controlled to be perpendicular to the top face of the high-speed train; when load shedding needs to be conducted on the high-speed train, the resistance increasing plate and incoming flow are controlled to be in a certain incidence angle state, the high lift device is controlled to rotate relative to the resistance increasing plate, and the deflection angle between the high lift device and the resistance increasing plate is changed so as to increase lift force. According to the resistance increasing and load shedding method for the high-speed train, resistance increasing in the train running process can be achieved, lifting force can be provided through the resistance increasing plate and the increasing device when the high-speed train accelerates or runs at a high speed, the load of the high-speed train and friction resistance to rails are reduced, and the service life of the high-speed train is prolonged. The rapid acceleration of the high-speed train is realized, and the consumption of electric power resources during high-speed driving is reduced.

Description

technical field [0001] The application belongs to the technical field of high-speed train design, in particular to a method and structure for increasing resistance and reducing load of high-speed trains. Background technique [0002] The design speed of modern high-speed trains can reach up to 480km / h, which requires them to face a deceleration process of rapid speed reduction before decelerating or stopping. Therefore, it is necessary to ensure sufficient resistance when braking and decelerating high-speed trains. In addition to the braking system, the corresponding resistance increasing device will be added to achieve the purpose of deceleration, which can save electricity and ensure the service life of train components. [0003] The existing resistance increasing plate is a resistance increasing device installed on the outside of the train. During the running of the train, the angle of attack of the increasing sun plate is controlled by the machine city device to increase...
