摘　　要：中间层隔震作为一种新型的隔震形式,在特殊结构或加固设计中有着应用优势。本文根据橡胶垫隔震结构的多自由度体系动力模型及状态方程,在Simulink环境下建立了基础隔震和中间层隔震结构的动力时程分析仿真系统,针对一栋框架结构的两种隔震形式进行了仿真计算,研究表明了两种隔震形式良好的隔震效果,同时证明了Simulink这种工具对结构动力系统仿真有着较高效率。The mid- isolation,a new type of isolation,has predominance in the application of special and reinforced structures. The Multi- Degree- Freedom dynamical model and state equation of the isolation structures were presented,and the dynamic time- history simulation analysis system were established by Simulink. Two types isolation of simulatlow and comparison of structures were confirmed it also shows that the simulink has a high effciency on the structwre dynamil system simulation. The Simulink is high effective in the simulation of structure dynamical system.
