Embodiment 1

[0054] Such as Figures 3 to 5 As shown, the execution unit of the present invention includes four kinds of jet actuators 5 according to their arrangement positions, which are respectively: the first jet actuator 1, which is arranged on the upper edge of the tail window on the inclined back of the high-speed vehicle; the second jet actuator 2. Arranged on both sides of the tail window on the inclined rear of the high-speed vehicle; the third jet actuator 3 is arranged on the upper edge of the vertical rear of the high-speed vehicle; the fourth jet actuator 4 is arranged on the vertical rear of the high-speed vehicle lower edge. The air source is connected to the four jet actuators through the flow controller, and the steady jet is ejected from the jet nozzle of the jet actuator 5, and the jet exit speeds of the four jet actuators 5 are all adjusted by the flow controller.

[0055] The directions of the jets generated by the four jet actuators 5 form a specific angle with the ...

Embodiment 2

[0059] Such as Figure 7 As shown, on the basis of Embodiment 1, each jet exciter 5 is installed on the high-speed vehicle high-speed rail. Since the high-speed rail is in operation, the wake flow structure at the tail is very similar to that of a car, so in this embodiment The layout position and jet injection angle of the jet actuator 5 can also be applied to the active drag reduction of high-speed rail. Further, the combined use of the best jet actuator 5 of the automobile in the present embodiment and the jet injection angle are used as a reference, and the jet injection angle of the high-speed rail tail jet actuator can be changed according to the situation in practical applications, so that Meet the demand for drag reduction.

[0060] Based on the above system, an artificial intelligence control method for a high-speed vehicle is produced when the system is used and executed.

[0061] The present invention adopts the method based on the steady jet generated by the jet ...

Abstract

The invention relates to the technical field of resistance reduction of high-speed carriers, in particular to an artificial intelligence control system and method for a high-speed carrier. The system comprises a sensing unit which collects gas path data of the system through a sensing element, judges the pressure intensity of the tail of the high-speed carrying tool according to the gas path data, and converts the gas path data into a voltage signal through a data collection system; the execution unit is used for controlling a flowing structure at the tail of the high-speed carrying tool by utilizing the voltage signal; and the control unit is used for controlling the surface pressure intensity of the tail part of the high-speed carrying tool according to the control target by utilizing a machine learning control algorithm. The control unit controls the execution unit according to data obtained by the sensing unit, the wake flow field structure is effectively changed through jet flow generated by the jet flow exciter, then the surface pressure intensity of the tail of the high-speed carrying tool is remarkably improved, and the aerodynamic resistance of the high-speed carrying tool is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of drag reduction for high-speed vehicles, in particular to an artificial intelligence control system and method for high-speed vehicles. Background technique [0002] In recent years, due to the rapid increase of fuel prices, the research and development of aerodynamic drag reduction technology for high-speed vehicles has become more important and urgent. The successful application of drag reduction technology for high-speed vehicles will bring huge benefits to the transportation industry. For cars running on highways, more than 60% of the driving resistance comes from the aerodynamic resistance on the car body. For every 10% reduction in the aerodynamic drag coefficient, the fuel consumption of the car can be reduced by about 7%. A high-speed rail with a speed of 250 kilometers per hour consumes more than 4,800 degrees of electricity per hour, while a high-speed rail with a speed of 350 kilometers per ho...
