Under the condition of given size and performance requirements of vibration isolation system,a new-type vibration isolator composed of air spring and rubber is designed,and three-dimensional simulation model of the new-type isolator is estab⁃lished from the perspective of finite element method.On this basis,the vibration isolation performance of the new-type vibration iso⁃lator under various working conditions is calculated and analyzed.The comparison between the calculated results and the design in⁃dexes shows that the new-type isolator can perfectly suit the requirements of physical size and vibration isolation performance,which aslo verifies the feasibility of the schematic design.The research of this paper can provide reference for the optimization or improve⁃ment of marine vibration isolator and the design of new-type vibration isolators.
