摘　　要： 结构图又称方框图,是控制理论进行控制系统分析的一种常用数学模型。针对阻尼连体结构振动控制系统详细介绍基于结构图的建模方法,探讨了求解该类结构动力特性的具体步骤。结合具体算例构建其结构图,进行基于Simulink的地震响应分析,体现了该方法的简便性。最后采用经典的Newmark-β数值算法,对基于结构图的仿真结果进行了验证,说明本文给定方法的正确性。 Block diagram also called block scheme is a common mathematical model to the control system analysis. The modeling method of damping connective structure vibration control system was introduced in detail based on the block diagram and the calculation steps to solve the dynamic characteristics of the structure was also discussed.The block diagram was established for seismic response analysis of the structure based on Simulink with a specific example, which embodies simplicity of the method.Finally,the simulation results based on block diagram were verified by using classic Newmark-βnumerical algorithm,which shows the correctness of the given method in this paper.
