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 known as the block diagram, is a commonly used mathematical model of control theory for control system analysis. Aiming at the vibration control system of damping Siamese structure, the modeling method based on the structure diagram is introduced in detail. The concrete steps to solve the dynamic characteristics of the structure are discussed. Combined with the concrete example, the structure diagram is constructed and the seismic response analysis based on Simulink is carried out, which shows the simplicity of the method. Finally, the classical Newmark-β numerical algorithm is used to verify the simulation results based on the structure diagram, which shows the correctness of the given method.
