【摘要】 介绍结构振动控制仿真分析软件TSHOW基于结构振动控制的算法和原理,建立了在无控、主动控制、隔振控制和半主动控制时结构运动的微分方程,并应用MATLAB控制系统工具箱(Control System Toolbox)中的函数,研制了仿真分析程序。对于实验结果,经TSHOW进行后处理,可以与仿真结果进行对比,从而分析控制实验的效果。仿真结果以图形方式显示,内容包括控制力时程、所选楼层的动力响应等,例如位移、速度、加速度时程。频域分析包括位移、速度、加速度的幅频响应曲线。所绘曲线的显示特性可以按照要求进行设置和调整。为了探求隔振层和控制装置的动力特性,利用图形技术,实现了层间恢复力-位移曲线的动态显示。更多还原

【Abstract】 A simulation software for structural vibration control is introduced.Based on structural vibration control theory and algorithm, the dynamic equation of motion of a building is established under different responses ,such as without control, active control, base isolation control and semi-active control.The dynamic investigated by comparing the post process experimental data with simulation results.To expolre the dynamic characteristic of base isolation and control device,their dynamic restoring force-displacement curve is depicted by using graphics technique.Simulation results are shown in figures,which include the dynamic responses of the building,such as time history of displacement,velocity, acceleration and control force.The frequency responses are plot by using transfer function and experimental data.The plot properties in the figure can be set and adjusted as expected.更多还原
