Abstract

The invention provides a high-acceleration high-stability high-temperature superconducting maglev vehicle system. The system comprises a train system and a rail system, wherein the train system comprises a train body, an electric brush arranged on the train body, a low-temperature refrigeration container arranged at the bottom of the train body, multiple columns of high-temperature superconductingcoils arranged in the low-temperature refrigeration container and a refrigeration system used for cooling the multiple columns of high-temperature superconducting coils, the rail system comprises a rail main body, a plurality of columns of power coils and a plurality of columns of suspension guide coils, in the direction perpendicular to the advancing direction of the vehicle body, the multiple columns of high-temperature superconducting coils, the multiple columns of power coils and the multiple columns of suspension guide coils are all symmetrical about the central axis of the vehicle body,the power coils and the high-temperature superconducting coils are arranged in a staggered mode, and the multiple columns of suspension guide coils are distributed on two sides of the multiple columns of high-temperature superconducting coils. The superconducting maglev train system with the structure is advantaged in that the utilization rate of a magnetic field and the power density of the motor can be effectively improved, and the train can have high stability under ultra-high-speed operation.

Description

technical field [0001] The disclosure belongs to the technical field of maglev trains, and specifically provides a high-acceleration, high-stability high-temperature superconducting maglev vehicle system. Background technique [0002] The linear motor is an important device of the drive system of the high-speed maglev train. It includes a stator fixed to the ground and a mover fixed to the train. During the running of the train, the electric energy can be directly converted into linear motion without other conversion equipment. of mechanical energy. Compared with traditional rotary motors, linear motors have the characteristics of simple structure, easy maintenance, no contact, low noise and more precise speed control. [0003] In recent years, with the continuous improvement of high-speed maglev train drive system's demand for high thrust, high precision and operational stability of linear motors, more and more experts have begun to pay attention to and study the developme...
