Microgravity experiment platform based on halbach array permanent magnets

Abstract

The invention provides a microgravity experiment platform based on halbach array permanent magnets. The microgravity experiment platform comprises an experiment table, a servo motor, the permanent magnets, a pressure sensor, a conductor supporting surface, a feedback controller, a power supply and a gap detector, a test main body is placed on the conductor supporting surface, the pressure sensor and the servo motor are arranged on the test main body, a gravity environment is monitored through the pressure sensor, and the permanent magnets are installed on a rotating shaft of the servo motor; the feedback controller is arranged at the upper part of the test main body and is connected with the pressure sensor, the servo motor and the gap detector; and the gap detector is installed on a spacecraft base and used for detecting the distance between the permanent magnets and the ground, so the dangerous situation that the permanent magnets rub against the ground under the road condition thatthe middle is high and the two ends are low is avoided in the driving process. Meanwhile, the terrain is pre-judged. The structure is simple, the gravity compensation precision is high, and favorableconditions are provided for experiments due to the specific physical properties of the halbach array permanent magnets.

Description

technical field [0001] The present invention relates to a gravity experiment platform, more particularly, it relates to a microgravity experiment platform based on halbach array permanent magnets. Background technique [0002] As we all know, the lunar environment has the characteristics of low gravity, and the lunar rover and other equipment in the lunar environment will be affected by low gravity. The difference in gravity is an important difference between the environment of the moon and the environment of the earth. The low gravity on the moon will directly affect the performance of the mobile system of the lunar exploration vehicle. Therefore, the establishment of a low-gravity experimental environment is of great significance for the performance test of the lunar rover's mobile system. [0003] At present, the low-gravity simulation methods mainly include: drop tower method, parabolic flight method, water flotation method, air flotation method and suspension method. ...

Problems solved by technology

However, this method cannot carry out the low-gravity simulation experiment of the whole vehicle. Usually, a single-wheel low-gravity simulation experiment is carried out, and then the weight is used to balance the five-sixths of the gravity of the wheel and the corresponding structure, thereby simulating the actual working conditions of the lunar vehicle in microgravity.
