Research on the Vibration Characteristics of Ship Foundation with Different Isolators Type

摘要：

The different type isolators can influence on vibration characteristics of ship foundation. The effect that isolators type to the ship foundation vibration is investigated based on the real ship data and the finite element method by the vibration theory. On the one hand, the effect of device excitation force to the foundation is not only related to the parameters such as rigidity and damp of isolators but also the natural frequency of device-isolator-foundation system. On the other hand, the effect is related to the isolators type. The effect law is shown that the isolators type had little effect on the vibration characteristics relatively when the excited frequency is lower and the effect is bigger when the frequency is higher. The effect is expressed prominent at the end of foundation.
