Description
Technical Field
The invention relates to the technical field of high-speed trains, in particular to a telescopic wing device for regulating and controlling aerodynamic force of a high-speed train, the high-speed train and a control method.
Background
At present, the running speed per hour of a high-speed train in China is between 200 and 400km/h, the running speed per hour of a plurality of railway lines is maintained between 300 and 350km/h, the running state of the high speed is maintained, and high requirements are put forward on wheel components of the high-speed train. The wheels are used as connecting parts between the train body and the steel rails, and the stability and the reliability of the wheels are important guarantee for the stable and comfortable running of the train. However, as a component of high speed operation, wheel wear is inevitable, especially when the train is running under heavy load, with more severe damage to the wheels. When the wheel is abraded greatly, the wheel hub tread is unsmooth and unsmooth, and then the problem of train running stability is brought, and even potential safety hazards are caused. In addition, the high-speed train line usually spans a very long distance and is influenced by different natural environments, some of the influences are not negligible, the strong wind environment is one of the influences, the strong wind environment needs to be considered, and otherwise potential safety hazards can be buried in the running of the train. Compared with the environment with zero wind speed, when a high-speed train runs in a crosswind environment, the aerodynamic characteristics of the high-speed train can be obviously changed, so that the aerodynamic load on the train and the acting force between wheel rails are obviously changed, and a crosswind effect is generated. When the effect is small, the caused transverse aerodynamic force may resonate with each aerodynamic torque, so that the structure of the train is subjected to fatigue failure; if the effect is increased, the dynamic characteristics between the train wheel rails are greatly different from the original design, so that the transverse overrun and derailment of the train are caused, and the life safety of people is directly threatened. When the high-speed train runs in some special environments, such as areas of super-large bridges, viaducts, tuyere areas in mountainous areas and the like, the crosswind effect is particularly strong, the transverse acting force is more obvious, and the possibility of derailment and overturning of the train is greatly increased.
In summary, it is very important to study how to reduce the pressure on the wheels of the high-speed train and reduce the lateral force on the high-speed train in the crosswind environment.
In order to ensure the reliability and stability of the operation of the wheel as much as possible, a method for detecting the wheel at regular time is generally adopted, and unqualified wheels can be replaced in time. However, since the wheels of the high-speed train are made of special materials, the manufacturing process requirement is high, and the cost is high, the economical burden is increased by replacing the wheels.
In order to avoid the derailment of the high-speed train in the crosswind environment as much as possible, the most direct method is to stop the train, but the method is obviously not matched with the future development of the high-speed train. In addition, according to the data of weather prediction, the train is subjected to deceleration operation in different degrees aiming at the crosswind environment of the obstructed wind speed, so that the traveling efficiency of people can be influenced to a certain extent, and the method belongs to an alternative scheme.
In the prior art, patents with publication numbers CN202175052U and CN202175053U adjust the pitch angle of the wing device according to different situations, so as to achieve the effect of generating lift or resistance by using the energy of the airflow, thereby achieving the purposes of reducing energy consumption and shortening braking distance. The above patent does not provide for the reduction of the crosswind effect. The patent with the publication number of CN112498386B is that a fish scale imitating device is arranged on one side of a train body, and the angle of the device is adjusted according to the cross wind direction and the wind speed, so that the flow direction of the airflow is changed, and the purpose of weakening the cross wind effect is achieved. However, the device can only prevent the cross wind action on one side of the train, and the device is arranged in the whole area on one side of the train body, so that the original design of the train, such as windows, doors and the like, is influenced, and the device is not easy to use in practice.
