Device for carrying out microgravity experiment by utilizing facility with height difference

Abstract

The invention discloses a device for carrying out a microgravity experiment by utilizing a facility with height difference, which comprises an experiment module, a hanging bracket and an elastic rope, the experiment module is connected to the hanging bracket through the elastic rope, the other end of the elastic rope is connected with a protection module, and the experiment module is arranged in the protection module; according to the microgravity experiment device, the protection module is arranged on the outer wall of the experiment module, when the experiment module falls to the critical point where the free falling motion is finished and the elastic rope is in a completely-stretched but not-stretched state, the experiment module continues to fall, and at the moment, due to the existence of the protection module, instantaneous acting force is provided for the elastic rope by the protection module; and meanwhile, the instantaneous counter-acting force given by the elastic rope to the protection module can be accepted by the protection module, and the protection module slowly releases the impact influence, so that the impact influence on the experiment module is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of microgravity, in particular to a device for carrying out microgravity experiments by utilizing facilities with a height difference. Background technique [0002] As we all know, the science of microgravity is a science gradually developed along with the exploration of space. The microgravity effect in the space environment produces many physical, chemical and life phenomena that are completely different from those on Earth; It is not easy to obtain a microgravity environment. Usually, it takes a lot of manpower, material and financial resources to build corresponding professional equipment, which leads to high costs for microgravity experiments, such as dropping wells or dropping towers in the prior art (about 1-4.5s microgravity time), parabolic aircraft (about 20s microgravity time), microgravity rockets (a few minutes to ten minutes of microgravity time) and various aircraft (about several days to seve...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the prior art is that it directly connects the equipment used for the microgravity simulation experiment with the elastic rope used for bungee jumping, and when the experimental equipment falls to the critical point where the free fall ends, the elastic rope is fully extended. But when it is not stretched, the experimental equipment continues to fall and will exert force on the elastic rope. Due to the coexistence of action force and reaction force, the elastic rope will produce a reaction force on the experimental equipment at this time, and the experimental equipment will do free fall. When the speed reaches the maximum, it is affected by the reaction force, which will have a large impact on the experimental equipment at this moment, causing the experimental objects in the experimental equipment to spill, break, and even damage the experimental equipment. Therefore, it is necessary to design the experimental equipment. A protective measure to avoid the above problems
