Abstract

The secondary vibration isolation may be used to abate sound transmission in solid in the application of damping and noise reduction treatment engineering, which can have an ideal effect. The secondary vibration isolation system has a natural low frequency so it can isolate low frequency vibration. The choice of vibration isolation frame mass or ratio of vibration isolation frame mass and unit mass is key technology. Resonant mass ratio range may be abtained by way of research on the relationship between frequency ratio and mass ratio. The relationship between vibration isolation efficiency and mass ratio may be figured out through the example. The ratio of vibration isolation frame mass in secondary vibration isolation affects system’s resonance frequency. Resonance frequency can be escaped when mass ratio is above 0.3. Better efficiency can be gained through big mass ratio when necessary.
