| Summary: | In order to study the influence of isolator arrangement on the vibration of the foundation in a marine gearbox，a gear system with single-stage isolation is taken as an example. The impedance model of gear pair，shaft，bearing，housing，isolator，and foundation is constituted considering the flexibility of subsystems，and the impedance synthesis approach is adopted to constitute the coupled impedance model. The influence of the span，non-symmetric arrangement，and number of isolator on the vibration isolation is studied. Results show that，slightly decrease the span of isolators is beneficial to vibration isolation，the symmetric arrangement of isolators is not the optimal scheme to reduce vibration，increasing the number of isolator does not always increase vibration，and the rib feature of housing and foundation cannot be ignored in the vibration isolation analysis. |
