基于自供电磁流变阻尼器的隔震高架桥半主动控制
|
摘要
为解决结构振动控制的能量源问题,提出了一种新型自供电MR阻尼器智能减振系统。该系统由电磁调节式MR阻尼器、齿条齿轮加速器、永磁电机与控制器组成。基于广泛采用的隔震高架桥两自由度线性模型,定义了位移控制性能评价指标,引入了在汽车悬架系统设计中常用的Sky-hook控制策略,对隔震高架桥的减震性能进行了仿真分析。结果表明:通过优化设计的参数,自供电MR阻尼器的LQR-Clipped半主动控制与Skyhook控制都可以完全达到其相应的采用外部供电的MR阻尼器的控制效果,且接近理想的主动控制结果。
A new self-powered vibration control system based on magnetorheological(MR) damper is presented to solve the problem of power source of structural control,which consists of four key parts: a current adjustment MR damper,a rack and pinion mechanism,a permanent magnet generator and a control circuit.Based on the widely used two-degree-of-freedom model of isolated elevated highway,the performance indices with displacement control are defined,and the skyhook control that is commonly used in vehicle suspension system design is introduced.Numerical simulations for seismic protection of elevated bridges equipped with this system are conducted.It is shown that both the LQR-clipped and skyhook control with self-powered MR damper can achieve the same performance as its corresponding control with external power supply,and even get close to that of ideal LQR active control.
