Description

technical field [0001] The invention relates to a space microgravity simulation experiment system, which is suitable for simulating space environment on the ground. Background technique [0002] As we all know, the space environment has the characteristics of microgravity, astronauts and aerospace equipment in space lose the effect of gravity, so before launching astronauts and aerospace equipment into space, it is necessary to carry out skill training for astronauts and aerospace equipment. No-gravity simulation experiment; since the ground environment is different from the space environment, how to simulate the space environment and reproduce the zero-gravity state on the ground has become a technical problem that needs to be solved urgently. [0003] At present, the methods commonly used in various countries in the world to simulate the space environment include: water flotation method, air flotation method, free fall motion and hanging wire gravity compensation method. ...

Problems solved by technology

When using the water flotation method to conduct experiments, it is necessary to immerse all the experimental objects in water, use the buoyancy generated by the water, and at the same time accurately adjust the buoyancy of the floater and the size of the counterweight to offset the gravity generated by the experimental objects, so the experiment is easily affected by water. The impact of resistance and turbulence, and the maintenance cost is high, and the sealing of the system needs to be guaranteed; the principle of the air flotation method is to use the gas pressure to float the object by the air film, so that the object can move freely in a certain space. Using this method When carrying out space weightlessness simulation experiments, the model is relatively simple, but the cost is high, the process is relatively complicated, and only plane experiments can be completed, etc.

When the object is in free fall, the object is in complete weightlessness, so the method of free fall can simulate the space environment well and reproduce the zero-gravity state, but the free fall method is expensive and the experiment time is short, so this method is difficult It has been promoted; the principle of the hanging wire counterweight compensation method is to use the weight of the counterweight to compensate the gravity effect of the experimental object through the pulley block. The advantage of the hanging wire counterweight system is that it can perform gravity compensation in three-dimensional space, and the experiment time is not limited. However, this method has shortcomings such as insufficient gravity compensation accuracy, and it is difficult to identify the dynamic friction of the suspension system and accurately compensate it in its control system.
