Abstract：In order to achieve simulation prediction of the isolation performance of rubber isolators,simulation and testing comparative research on the vibration transmissibility of standard specimens were conducted.Firstly,a compression test was conducted on the standard specimen to obtain pressure deformation data.Based on the theory of the large deformation,the data was processed to obtain the true stress-strain curve.The Mooney-Rivlin model was chosen to define the material properties.Secondly,a vibration transmissibility testing system was established,an exciter to excite the standard sample was used,and the measured vibration transmissibility curve was obtained.Then,a simulation model based on the testing system was built,and the simulation transmissibility curve based on the transient dynamic analysis was obtained.Finally,the test results were compared with the simulation results to achieve the simulation prediction of the rubber isolation performance.The results show that the simulated isolation rate curve is highly consistent with the test results,with a peak frequency error of only 4.8%,which can achieve the simulation prediction and provide a simulation guidance for the optimization design and performance improvement of isolators.
