Novel superfast train by utilizing ground effect pneumatic suspension and electromagnetic propulsion

Abstract

The invention discloses a novel superfast train by utilizing ground effect pneumatic suspension and electromagnetic propulsion, and belongs to the field of ground effect aerodynamics and superfast trains. According to the novel superfast train, pneumatic modification is conducted to the train bottom of an existing magnetic suspension train, the train bottom forms a continuous smooth contracted type curved surface, and a contracted air passage is formed by the contracted curved surface and the surface of a rail. The sectional surface of the train head in an entrance portion is the largest, and the sectional surface of the train tail in an exit is the smallest. Electromagnetic force is replaced by pneumatic lifting force generated by the ground effect so as to suspend the train, the advantages that the existing magnetic suspension train is low in resistance and slow in speed are reserved, the problem of power energy consumption of magnetic suspension is improved, the weight of vehicle-mounted superconduction relative devices is reduced at the same time, energy consumption of the train in the process of superfast running is reduced and efficiency of transporting is improved.

Description

technical field [0001] The invention belongs to the field of ground-effect aerodynamics and high-speed trains, and in particular relates to a novel ultra-high-speed train utilizing ground-effect aerodynamic suspension and electromagnetic propulsion. Background technique [0002] In 1964, Japan built the world's first high-speed railway, which revitalized the railway transportation industry, which was a sunset industry at that time. Subsequently, high-speed railway technology developed rapidly, and various high-speed train concepts emerged continuously. Current high-speed trains mainly include two types: wheel-rail and suspension. [0003] Wheel-rail high-speed trains are the main type of high-speed trains currently in use, relying on the friction between the wheels and rails to propel the train forward. The wheel-rail high-speed train has reached the highest test speed of 574.8km / h, and the technology is relatively mature. However, from a longer-term perspective, the whee...
