基于大跨空间网架结构主动控制的新型超磁致伸缩材料作动器优化配置研究
|
摘要
首先基于新型超磁致伸缩材料(GMM)设计了一种新型作动器,并对其进行了试验研究,获得了其本构方程.利用结构振动模态方程提出了遗传优化算法中的主要参数——优化性能指标;利用MATLB所提供的遗传算法工具箱并结合前述结论确定了作动器最优布置位置.最后利用所编制的LQR主动控制程序对一平板网架结构进行了不布置及随机布置与优化布置该作动器下的地震响应对比分析.结果表明:优化布置该新型作动器后结构地震响应明显减弱,从而验证了该新型作动器在结构主动控制中应用的有效性及遗传优化算法对于此类问题进行研究的可行性.
A new type of actuator was designed based on the new giant magnetostrictive material(GMM).With experimental research,its constitutive equation was obtained.The optimized performance index which is the main parameters of the genetic optimization algorithm was put forward based on the structural vibration modal equation.The optimal placement position of the actuator was determined by using genetic algorithm toolbox in MATLAB software and the foregoing conclusions.Lastly,the seismic response of the plane grid structure under no layout,random layout and optimization layout of the actuator were compared using the prepared LQR active control program.The results showed that the structure earthquake response was significantly reduced under the optimization layout of the new actuator.The validity of the application in active structural control with the new actuators is verified as well as the feasibility for such problems with genetic optimization algorithm.
