Design and Test Analysis of Fluidlastic Isolator

The work aims to carry out the design and test verification of fluidlastic isolator. Based on the anti-resonance principle, a dynamic analysis model of the fluidlastic isolator was established and its dynamic equation was derived. The relationship between the vibration isolation frequency of the fluidlastic isolator and related parameters was established and the model of fluidlastic isolator was designed according to related parameters. Then,the dynamic performance test was carried out to the fluidlastic isolator. The performance of fluidlastic isolator was verified by dynamic stiffness test and transmittance test. The test results verified the high static stiffness and low dynamic stiffness of the fluidlastic isolator at the vibration isolation frequency. The design of the fluidlastic isolator is realized, and the fluidlastic isolator achieves a 60% vibration reduction effect at the vibration isolation frequency point.
