The ship pipeline vibration isolation device is very important for reducing the vibration transmission of the pipeline and improving the sound stealth performance of the ship.The efficient pipeline vibration isolator can effectively reduce the vibration and noise of the pipeline.In this paper,a new type of ship pipeline isolator is designed,and a prototype of the pipeline isolator device is prepared for the seawater pipeline system.In order to verify the performance of the new pipeline vibration isolation device,the static stiffness,natural frequency,vibration isolation effect,impact resistance and damage load test of the pipeline vibration isolation device were carried out.The experimental data show that the pipeline vibration isolator designed in this paper has great static and dynamic mechanical properties,the research results of this paper also provide technical guidance for the design of pipeline vibration isolator.
