Vacuum pipeline fluid film suspension vehicle system

Abstract

The invention relates to a vacuum pipeline fluid film suspension vehicle system, which combines a low-pressure vacuum pipeline with a fluid film suspension vehicle, and the fluid film suspension vehicle directly forms a pressure fluid film between a chassis and a track surface by virtue of a fluid dynamic pressure effect so as to suspend and run in the vacuum pipeline. The density of gas in the pipeline, the viscosity of fluid in the fluid film and the boiling point of the fluid in the fluid film are reduced by reducing the gas pressure in the vacuum pipeline. The pressure difference resistance in the driving process can be reduced by reducing the gas density; the viscosity resistance on the train chassis can be reduced by reducing the viscosity of the fluid in the fluid film; the reduction of the boiling point of the fluid in the fluid film can promote the fluid film to automatically generate a phase change process under the pneumatic heating action so as to increase the thickness of the fluid film, improve the loading capacity, reduce the viscosity of the fluid film and reduce the viscous resistance of a train chassis. According to the vacuum pipeline fluid film suspension train, the running resistance can be reduced to the maximum extent, and high-speed, efficient and stable suspension running of the train is achieved.

Description

technical field [0001] The invention relates to a vacuum pipeline fluid film suspension vehicle system. The system combines a low-pressure vacuum pipeline with a fluid film suspension vehicle, which can significantly reduce the resistance during driving, has better high-speed suspension stability, and ensures the high-speed, high-speed operation of the train. Efficient and stable suspension driving. Background technique [0002] It has always been the dream of human beings to suspend vehicles on the track and realize high-speed and high-efficiency driving. Reducing train running resistance to the greatest extent is a key technical problem that must be solved to realize this dream. [0003] The total resistance of conventional trains during running mainly comes from mechanical friction resistance and air resistance. Mechanical friction resistance can be eliminated by using suspension technology. However, the magnitude of air resistance is proportional to the square of the ru...

Problems solved by technology

However, there are still two key problems in this system that are difficult to overcome: first, the existence of the compressor increases the weight of the train and the complexity of the system, and generates a lot of noise during driving; A large amount of gas is inhaled in the tunnel to form an air cushion of sufficient thickness. The gas supply of the air cushion and the stability of the air cushion during high-speed driving are the key technical issues that need to be solved for the vacuum pipeline startup suspension system.
