采用模拟电路对结构振动控制系统进行仿真分析,将结构振动控制系统的结构动力参数的调整转换为模拟电路中电路元件参数的调节,为振动控制系统的研究与分析提供了较大的方便。针对建筑结构振动控制系统,详细介绍了模拟电路的设计方法,并结合一个具体算例构建其模拟电路进行仿真分析,体现了该方法的简便性。采用经典的Newmark-β数值算法对基于模拟电路的仿真结果进行了验证,说明了本文给定方法的正确性。
The simulation analysis of structure vibration control system is carried out by analog circuit, and the adjustment of structural dynamic parameters of structural vibration control system is converted into the adjustment of circuit element parameters in analog circuit, which provides great convenience for the research and analysis of vibration control system. Aiming at the vibration control system of building structure, the design method of analog circuit is introduced in detail, and the simulation circuit is constructed based on a concrete example to illustrate the simplicity of the method. The classical Newmark-β numerical algorithm is used to verify the simulation results based on analog circuits, which shows the correctness of the method given in this paper.
