| Abstract: | Based on the dynamic characteristics obtained with three dimension finite element method, the reduced mechanical model and parameters of lift ship structure can be modified and obtained . Simulated analysis shows that the reduced mechanical model can represent preferably the characteristics and earthquake responses. The reduced mechanical model can be used to control the seismic whiplash effect of top building of lift ship structure with intelligent control methods. Based on this model, the reduced mechanical model installed roof intelligent isolation can be established. |
