Problems solved by technology

[0004] However, due to the special structure of the maglev integrated structure, its parameters are related to the movement of the train and are functions of the vehicle's forward time and space. Therefore, it is relatively difficult to analyze the three-dimensional force

Embodiment Construction

[0056] The present invention will be further described in detail below in combination with specific embodiments.

[0057] 1. Maglev integrated structure.

[0058] The structure diagram of the linear magnetic levitation motor integrating the functions of traction, levitation and guidance is as follows: figure 1 shown. The schematic diagram only draws a pair of poles of the linear magnetic levitation motor, wherein the 8-shaped coil excited by U, V, W three-phase alternating current represents the primary of the linear magnetic levitation motor. Each small integrated unit of the secondary of the linear magnetic levitation motor is called an 8-character coil because it is similar to the Arabic numeral "8". The 8-shaped coils on both sides of the track are connected by wires, and it is recommended to be installed on both sides of the train running track. The superconducting coil represents the secondary of the linear maglev motor, and it is recommended to be installed on both s...

Abstract

The invention relates to a numerical method for calculating the electromagnetic force of an 8-shaped coil suspension system, which comprises the following steps: in order to solve the traction force,suspension force and guiding force of a magnetic suspension integrated structure, firstly analyzing the overall structure of the magnetic suspension structure, simplifying a special structure, dividing the special structure into a plurality of simple model sets, and finally superposing the simple model sets. The method has the following advantages: (1) the numerical method can accurately calculatethe thrust, suspension force and lateral force of the 8-shaped coil; and (2) the numerical method occupies less computer resources and is rapid to solve.

Description

technical field [0001] The invention relates to a numerical method for calculating the electromagnetic force of an 8-shaped coil suspension system, which belongs to the field of rail transit and can be used for solving the thrust, suspension force and lateral force of a maglev integrated system. Background technique [0002] In the field of rail transit, non-contact maglev transportation has become an important direction for the development of modern rail transit due to its low noise, no wear and high safety, which also meets the development requirements of green travel. In order to ensure the safe control of the motor, it is particularly important to solve the traction force, suspension force and guiding force. [0003] In the existing high-speed maglev system, the train is driven by a linear synchronous motor: that is, it is realized by the primary coil installed on the ground track and the secondary installed on the maglev train. The levitation and guidance are realized ...
