High-efficiency energy-saving technology for bullet train

Abstract

The invention provides a high-efficiency energy-saving technology for a bullet train. The high-efficiency energy-saving technology for the bullet train has small resistance and large thrust force, and is technologically characterized in that: the front end resistance surfaces of various express trains, bullet trains and the like are provided with turbulent current recesses, or turbulent current grooves are formed by extending backwards from the turbulent current recesses. The high-efficiency energy-saving technology is characterized in that: the resistance surfaces of the front ends of train heads or train bodies of various express trains and bullet trains are provided with at least one turbulent current recess which is opened upwards; 1, at least one turbulent current groove is formed on the front end resistance surface in an extending manner; 2, at least one turbulent current groove is formed on the front end resistance surface in gradually magnifying manner; 3, at least one step-shaped turbulent current groove is formed on the front end resistance surface in a stepwise extending manner; 4, at least one step-shaped turbulent current groove is formed on the front end resistance surface in a stepwise gradually magnifying manner; and 5, the bottom of the turbulent current groove or the step-shape turbulent current groove is provided with carinate wings which project along the central line of the turbulent current groove close to the center of the recess and incline downwards at two sides.

Description

Technical field: [0001] The invention relates to a high-efficiency locomotive boosting technology, which is used on the front end or top resistance surface of the locomotive of high-speed trains running on various railways. Background technique: [0002] At present, the front end or top resistance surface of the high-speed train running on various railways adopts ordinary plane or curved surface. This kind of structure has high resistance and has no function of changing resistance into power. Or the wasted power is very large. When various high-speed trains and bullet trains move at high speed, the resistance generated by the air flow field becomes a large factor of power consumption. According to the current dynamic principle, it can no longer meet the needs of ultra-high speed movement. When the moving object has a single structure, the resistance wave it receives becomes a resistance body with the most perfect structure and the strongest resistance, so the resistance it r...

[0002] At present, the front end or top resistance surface of the high-speed train running on various railways adopts ordinary plane or curved surface. This kind of structure has high resistance and has no function of changing resistance into power. Or the wasted power is very large. When various high-speed trains and bullet trains move at high speed, the resistance generated by the air flow field becomes a large factor of power consumption. According to the current dynamic principle, it can no longer meet the needs of ultra-high speed movement. When the moving object has a single structure, the resistance wave it receives becomes a resistance body with the most perfect structure and the strongest resistance, so the resistance it receives is also the largest. Only by breaking the structure of the resistance body, by changing the structure of the resistance wave or the force body , that is, by changing the force on the front end or top of the front of the car, the resistance can be effectively reduced and the fuel consumption can be reduced
