MULTI-DEGREE-OF-FREEDOM ANIMAL CENTRIFUGE WITH FOUR
ROTATING ARMS
[OI] The present invention belongs to medical experimental equipment for centrifuging of animals, which is used for performing a medical experiment for centrifuging animals, and relates to a multi-degree-of-freedom animal centrifuge with four rotating arms.
[02] With the vigorous development of the aerospace industry in China and the gradual completion of China's space station plans, the maneuverability and combat performance of a new generation of fighter jets have become higher, and manned spacecrafts and launch vehicles are launched more frequently. Therefore, if a pilot is exposed to a high G-value environment for a long time, it may cause problems such as G-force induced Loss of
Consciousness (G-LOC) of the pilot, which will seriously endanger the life of the pilot and affect a flight mission. If a high G-value experimental study is carried out on a pilot, study materials after the experiment are difficult to obtain and the pilot's health is also seriously damaged.
[03] Therefore, animals are used to replace people. The body of an animal is centrifuged to study a series of adaptive changes in various physiological systems in the body of the animal, so as to provide an experimental basis for further study. This is also an important means in aerospace medical study. Both an animal centrifuge and a human centrifuge belong to biological centrifuges. However, compared with human, animals have higher tolerance and can withstand a higher acceleration and an acceleration change rate.
Therefore, the animal centrifuge has a higher requirement for the comprehensive performance than that of the human centrifuge. As important equipment in the aeronautical medical study, the animal centrifuge is of great significance for medical researchers to build a +Gz acceleration animal model and carry out a pathological study under an aeronautical physiological condition.

[13] Beneficial effects

[15] Compared with the prior art, the present invention at least has the following beneficial effects: The biggest advantage of the four-rotating-arm system of the present invention is that two groups of contrast experiments can be carried out at one time, and one group contains two rotating arms. Experimental data of each time is composed of two pieces of animal fixing platform data of diagonals. In this way, the experimental efficiency is greatly improved, and it helps a researcher to better design an experimental scheme.
When the structure meets a strength requirement, the rotating arms are formed by bending a steel plate. A plate is bent into a C shape, and the elliptical holes are formed in the top and the two sides according to a certain ratio, so that the weight of each rotating arm 1s 5 reduced, and the wind resistance is reduced. Reinforcing ribs are provided at tail ends of the rotating arms to improve the rigidity of the rotating arms. Such a structure is simple and good in integrality and has a low welding machining requirement when it is compared with a truss structure. Furthermore, in a running process, the phenomenon that this structure will shake due to non-uniform weight distribution caused by welding is avoided, and the accuracy and the reliability of the rotating arms are guaranteed.
[16] In the biaxial-rotating animal carrying platform system, the step motor push rod is fixed to the swing plate and the rotating arms respectively through the two adjustable L plates, so that an extreme angle of swing can be changed by adjusting size parameters of the two L plates. By the adoption of the step motor push rod, the structure is simple, so that the complicated circular motion is converted into a simple linear motion. Furthermore, the step motor push rod has a limiting function, so that the safety and reliability of equipment are improved. The elongated holes are uniformly distributed on the animal fixing platform, so as to reduce the weight as much as possible and reduce the moment of inertia; and to conveniently fix an experimental animal by a binding method. The peripheral edges of the animal fixing platform are folded to improve the rigidity of the platform, so that the platform is hard to deform during use and working.
