Vacuum pipeline magnetic suspension train hybrid EMS supporting structure

Abstract

The invention discloses a vacuum pipeline magnetic suspension train hybrid EMS supporting structure which comprises a vacuum pipeline, a capsule train and a supporting guide part. The capsule train isarranged in the vacuum pipeline in a sleeved mode; a rail armature is arranged on the inner wall of the vacuum pipeline in the length direction of the vacuum pipeline; and the supporting guide part is arranged between the vacuum pipeline and the rail armature. The supporting guide part comprises an electromagnetic coil, an electromagnetic core, a permanent magnet, and safety supporting wheels; the electromagnetic core is arranged at the upper end of the capsule train; the safety supporting wheels are arranged at the lower end of the capsule train; the permanent magnet and the electromagneticcoil are arranged on the electromagnetic core; and the permanent magnet meshes with the rail armature. Zero power suspension is achieved, power consumption of the system is greatly lowered, ampere-turns needed by the coil is reduced, and cost of the train and rail is lowered. The electromagnetic EMS partially applies active control to provide suspension damping, and therefore the train runs more smoothly, comfort is better, space utilization is improved, suspension power consumption is lowered, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a hybrid EMS support structure for a vacuum tube maglev train. Background technique [0002] The vacuum tube maglev train system is to run the maglev train in a sealed pipeline that is pumped into a near vacuum. Its key technologies include: vacuum technology, traction motor technology and maglev train technology. The core of the maglev train technology is the suspension support technology. At present, the vacuum tube maglev support scheme is roughly the same as that of the conventional maglev train, and most of them are concentrated in the electromagnetic suspension (EMS), permanent magnetic suspension (PMS), electric suspension (EDS), and high-temperature superconducting suspension (HTS); Magnetic levitation (EMS) is to use the attraction force between the constant electromagnet and the strong magnet to achieve levitation.

Problems solved by technology

At present, the vacuum tube maglev support scheme is roughly the same as that of the conventional maglev train, and most of them are concentrated in the electromagnetic suspension (EMS), permanent magnetic suspension (PMS), electric suspension (EDS), and high-temperature superconducting suspension (HTS); Magnetic levitation (EMS) is to use the attraction force between the constant electromagnet and the strong magnet to achieve levitation. Now this structure technology is relatively mature, controllable and stable, but the levitation force is completely provided by the electromagnetic force, which requires a considerable amount of energy. The coil current can generate enough levitation force, so the levitation energy consumption of the maglev train is relatively large, and the control system is relatively complicated; the permanent magnetic levitation (PMS) uses the attraction or repulsion force between permanent magnets to achieve levitation, with less power consumption but Instability requires the introduction of other active controls or constraints to achieve stable suspension, and permanent magnets placed in the open air may attract other ferromagnetic substances and easily cause train accidents; electric suspension (EDS) uses a changing electromagnetic field to induce in a metal conductor Eddy current, the eddy current magnetic field is opposite to the direction of the original excitation magnetic field, thereby generating repulsive force to achieve levitation. The original excitation magnetic field can be excited by a constant conductive electromagnet, permanent magnet or superconducting magnet, with low cost and low energy consumption, but the levitation force increases with the speed and increase, so it cannot be suspended at rest or at low speed; high-temperature superconducting suspension (HTS) is a self-stabilizing passive suspension technology that uses the pinning characteristics of high-temperature superconducting bulk materials to achieve no control, but its construction cost is high and technical difficulties High, difficult to maintain, still in the experimental research stage
