Technical Field
The invention belongs to the technical field of experimental instruments, and particularly relates to a horizontal vibration reduction platform for providing elastic rigidity and damping by using an internal glycol solution based on a corrugated ring structure.
Background
Vibration source devices are often found in medical or biological laboratories, as well as various types of centrifuge devices that are not necessarily in complete equilibrium with the tubes and solutions due to high rotational speeds during operation. Therefore, serious horizontal vibration occurs during work, the energy of vibration excitation is sharply increased along with the increase of the rotating speed, and if the vibration excitation is not controlled, larger noise and vibration transmission can be generated, so that the physical and psychological health of experimenters and the working reliability of other precise instruments and equipment are influenced.
At present, no effective vibration isolation measures exist in medical and biological laboratories for the vibration source equipment, and most of the vibration isolation measures adopt a mode of directly placing on a workbench or the ground or only adopting a simple rubber vibration isolation block for supporting to isolate vibration. The elastic elements such as rubber or springs and the like usually play a role in storing vibration energy in vibration reduction, and the damping of the elastic elements is very small, so that vibration energy cannot be basically dissipated, therefore, the vibration isolation mode has a limited vibration reduction effect and cannot meet the requirement of broadband vibration isolation of a general centrifuge at 100Hz to 3000 Hz. Therefore, it is necessary to improve the vibration isolation measures and structures of vibration source devices such as centrifuges in medical and biological laboratories, so that the vibration isolation devices can better achieve the vibration isolation effect.

Example 1
A corrugated ring hydraulic vibration reduction platform is characterized in that vibration source equipment is placed on a circular working table top 1, and the outer side of the working table top 1 is connected with an inner corrugated ring 3 in a rubber layer vulcanization mode. The inner side corrugated ring 3 has an upper layer structure and a lower layer structure, and is fixedly connected with the outer side of the working table top 1 in a vulcanization mode. The outer side of the corrugated ring is provided with a throttling ring 5 which is also connected in a rubber layer vulcanization mode, so that the outer side of the working table surface 1, the inner side corrugated ring 3 with a two-layer structure and the throttling ring 5 jointly form an annular space structure, namely an inner annular liquid chamber 4, and the inside of the liquid chamber is filled with 80% glycol aqueous solution.
The outer side of the throttle ring 5 is connected with an outer corrugated ring 8 in a vulcanization mode, the outer side of the outer corrugated ring 8 is of a closed structure, the outer corrugated ring and the outer corrugated ring form an outer annular liquid chamber together, and the chamber is filled with 80% ethylene glycol aqueous solution. The outer ring guard plate 7 is positioned at the outermost side of the whole vibration damping platform and is in bolted connection with the throttling ring 5 through 8 holes in the periphery, and finally, the annular rubber hydraulic vibration damping platform with good horizontal vibration damping performance is formed as shown in fig. 2.
The specific implementation process and the vibration isolation principle are as follows:
when vibration source equipment placed on the circular worktable surface 1 generates vibration excitation, the vibration is transmitted to the inner corrugated ring 3 through the worktable surface 1, the inner corrugated ring 3 is elastically deformed, the vibration energy is stored, and meanwhile, the inner liquid ring chamber 4 is deformed to promote the liquid in the inner corrugated ring to flow. When the vibration frequency is low, the pressure difference inside the inner annular liquid chamber 4 is small, the liquid basically flows only in the inner annular liquid chamber 4, the flowing state of the liquid is turbulent, and the liquid irregularly flows to generate a standing wave phenomenon, so that energy loss is caused. At the same time, the flowing liquid rubs against the chamber walls to produce energy losses, and the liquid flow phenomenon provides damping, but in this case the damping provided by the liquid is less. When the vibration frequency is high, the local pressure difference in the liquid is large, a large part of the liquid flows between the inner ring liquid chamber and the outer ring liquid chamber through the throttling channel 13 on the throttling ring 5, the outer side corrugated ring 8 is promoted to expand and compress, the throttling channel is relatively narrow, the resistance of the liquid flowing in the throttling channel is large, the energy loss is large, large damping is provided for the whole vibration damping platform, and the vibration is helped to be quickly attenuated. When the vibration frequency is high and the amplitude is large, the amount of liquid flowing into the outer annular liquid chamber is large, the outer corrugated ring is enabled to be expanded excessively, the outer diameter of the outer corrugated ring reaches the outer annular protection plate 7 to be limited, and therefore the soft limiting and protecting effects on the vibration isolation platform and corresponding vibration source equipment are achieved. In general, the corrugated ring hydraulic vibration reduction platform provided by the invention can meet the vibration isolation requirement under broadband and large excitation.
It is to be noted that the foregoing description is only exemplary of the invention and that the principles of the technology may be employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
