Vibration isolation laboratory with air bags and passive dampers

Abstract

The invention discloses a vibration isolation laboratory with air bags and passive dampers. The vibration isolation laboratory with the air bags and the passive dampers comprises a vibration isolationlaboratory space 1, a laboratory support frame 2, air springs 3, a rubber plate 4, the lateral airbag 5, concrete reinforcement walls 6 and the electromagnetic dampers 7. According to the vibration isolation laboratory with the air bags and the passive dampers, the rubber plate serves as a primary vibration isolation system; the air springs lifts up the entire vibration isolation laboratory spaceto form a secondary vibration isolation system; the electromagnetic dampers releases vibration energy in the form of heat energy instead in a passive damping consumption manner to achieve effective passive vibration isolation effects, and accordingly the combined vibration isolation design can achieve good overall vibration isolation effects, isolates external micro-vibration and provide an idealenvironment for high-precision sensor detection.

Description

technical field [0001] The invention relates to the technical field of precision laboratory vibration isolation, in particular to a vibration isolation laboratory with an airbag plus a passive damper. Background technique [0002] With the advancement of science and technology, ultra-precision machining and measurement technology has developed rapidly. Ultra-fine processing, testing and scientific experiments put forward strict requirements on environmental vibration, especially large-scale ultra-precision photoelectric measuring instruments have higher and higher requirements for anti-micro-vibration. In ultra-precision measurement and control, the measurement and control accuracy of precision instruments is not only related to the accuracy of the instrument itself, but also the influence of many factors such as vibration, temperature, and electromagnetic interference in the surrounding environment is also a key link in determining the accuracy of measurement and control. ...
