Analysis and Experiment Research on Two Layers Vibration Isolation of Diesel Generating Set in "Superiority" Oil Tanker

The dynamic characteristics of the two-layer vibration isolation and the transmission function curves obtained under different ratio mass and rigidity are mainly discussed. For the two-layer vibration isolation, it is shown that the many benefits of reducing vibration energy transmission and improving the isolation effect when rigidity ratio increases or mass ratio decreases as possible. It is proved by the actual test that there are more benefits for two-layer vibration isolation system than single layer vibration isolation system.
