摘要
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 analog circuits was used in simulation analysis of the structure vibration control system,the regulation of circuit element parameters in analog circuit insteads of the adjustment of dynamic parameters of structure vibration control system,which is very convenient on the study and analysis of the structure vibration control system.The design method of the analog circuit diagram was introduced in detail based on structural vibration control system.The simulation is carried on through building the analog circuit diagram aiming at an example,which embodies simplicity of the method.The simulation results based on analog circuit diagram are verified using of the classic Newmark-β numerical algorithm.The correctness of the method given in this paper was shown.
