Simulation research on the performance of pipeline vibration isolators based on the rubber hyperelasticity constitutive model
The use of pipeline vibration isolator is an effective means to reduce the transmission of vibration and noise of the ship pipeline system,but the ship pipeline is more complex need to be designed according to the specifications of the pipeline series model vibration isolator.How to effectively forecast the performance of different specifications of pipeline vi-bration isolators in the actual use of the process is the design of pipeline vibration isolators urgently need to solve the prob-lem.To this end,this paper fits the rubber hyperelasticity intrinsic parameters through rubber tensile test,simulates the per-formance of vibration isolators(static deformation and natural frequency)by using the finite element method,and verifies the results of the calculations by tests.The results show that the error rate of both numerical simulation and experimental results of the designed vibration isolator is less than 10％.It is proved that this parameter can effectively predict the performance of multi-specification vibration isolators.The research in this paper provides guidance for the series design of ship pipeline vi-bration isolators.
