Embodiment Construction

[0042] The invention provides a single-axis full-physics simulation maglev platform for realizing full-physics simulation of moving bodies such as spacecraft. Such as figure 1As shown, the single-axis full-physics simulation maglev platform is mainly composed of six units: structural support unit, bearing unit, axial maglev unit, sensor unit, gap adjustment and control unit, and axial surface unit. Among them, the structural support unit includes a base 11, a linear bearing seat 17 and a pad iron 23; the bearing unit includes an upper bearing cover 7, an upper bearing 8, a lower bearing 9, and a lower bearing cover 10; the axial magnetic levitation unit includes an upper magnet support 2 , the upper magnet 3, the lower magnet 5 and the lower magnet support 6; the sensor unit includes the sensor cable through hole 12, the upper sensor support 13, the upper sensor 14, the lower sensor 15 and the lower sensor support 16; the gap regulation unit includes a linear guide Shaft 18, ...

Abstract

The invention discloses a single shaft full-physical emulated maglev stage which is mainly used for processing full-physical emulation for the control system of the spacecraft and other mobiles. The single shaft full-physical emulated maglev stage comprises a structural supporting unit, a bearing unit, an shaft directional maglev unit, a sensor unit, a gap adjusting and controlling unit and shaft surface unit. The shaft surface unit, the upper sensor, the upper magnet and the rotor potion of the bearing unit are the rotating potion of the maglev stage; the structural supporting unit, the lower sensor, the lower magnet and the stator potion of the bearing unit, gap adjusting unit are the static potion of the maglev stage; the magnetic force generated between the upper magnet and the lower magnet arranged in the shaft directional maglev unit balances the influence by the gravity to the rotating position can rotate without any frictions around the core shaft. As a free rotating stage, the invention overcomes the shortcomings of larger frictions of the general semi-physical emulated mechanical rotating stage, assuring the control system emulated object having the characteristic of automated close loop.

Description

technical field [0001] The invention relates to a physical simulation test bench applying the principle of maglev, in particular to a fully physical simulation maglev test bench adopting a single-axis structure, which belongs to the technical field of testing equipment. Background technique [0002] There are usually three approaches to scientific research: theoretical derivation, scientific experiment and simulation. The application of various simulation technologies plays an indispensable role in scientific research. Especially in the field of control technology research, the use of various simulation technologies is an important means for theoretical research and engineering practice. [0003] At present, simulation technology is mainly divided into two categories: computer simulation and physical simulation. Computer simulation is essentially mathematical simulation. It first establishes the mathematical model of the system, converts the mathematical model into a simul...
