This series of vibration isolation bars is the ideal vibration isolation tool when the environmental vibration is close to or exceeds the allowable specifications of the instrument. It can be composed of two or more modules, which can isolate the vibration of 6 degrees of freedom. The system starts to isolate the vibration at 1HZ , and the vibration rapidly attenuates as the frequency increases, and it can reach 95% attenuation at 10HZ . Vibration isolation bars are usually used in pairs, according to different loads, the number of vibration isolation bars can be freely assembled to achieve the purpose of vibration isolation.
