Micro-gravity environment simulation driving mechanism

Abstract

The invention relates to the technical field of space ground simulation balance gravity, in particular to a micro-gravity environment simulation driving mechanism. The mechanism comprises an air floating platform, an air floating supporting mechanism and a target star simulator, wherein the air floating supporting mechanism is arranged on the air floating platform. The air floating supporting mechanism comprises a base frame body, air feet, a driving wheel assembly, a braking suction cup assembly, a supporting frame body and a plurality of frame balancing weights, wherein the air feet, the driving wheel assembly and the braking suction cup assembly are arranged at the bottom of the base frame body, the supporting frame body is arranged on the base frame body, and the target star simulator is arranged on the supporting frame body. The plurality of frame balancing weights are distributed on the base frame body and the target star simulator and are used for integrally balancing the base frame body and the target star simulator. The mechanism can simulate the plane movement of a satellite in a zero-gravity environment of outer space, eliminates the interference of the friction force between the satellite and the ground when related experiments are carried out on the ground, and facilitates the movement of the satellite on the smooth ground through the driving wheels.

Description

technical field [0001] The invention relates to the technical field of space ground simulation balance gravity, in particular to a microgravity environment simulation driving mechanism. Background technique [0002] Currently, there are three methods for simulating weightlessness. One is to use falling wells and falling towers to do free fall, or use airplanes to do parabolic flight to obtain a short-term gravity-free environment. The second is to use the weightless water tank to offset the gravity by using the buoyancy of water. The 3rd, suspension method, utilize counterweight to offset the gravity of aircraft self by rope mechanism and pulley block. But the first method can only simulate short-term weightlessness, generally no more than 30s. The second method requires the construction of a large pool, and the underwater environment has great restrictions on the experiment, such as the satellite is not waterproof, and it is inconvenient for the experimenters to work.

But the first method can only simulate short-term weightlessness, generally no more than 30s

The second method requires the construction of a large pool, and the underwater environment has great restrictions on the experiment, such as the satellite is not waterproof, and it is inconvenient for the experimenters to work, etc.

In the third method, the truss mechanism supporting the rope is complex and occupies a large area. The rope follow-up mechanism is generally supported by mechanical bearings, and the movement friction is large, which seriously affects the accuracy of the experiment. During the follow-up process of the flexible cable, the subsequent movement and flexible vibration Coupling factors such as all have adverse effects on balance gravity
