摘要:
提出结构动力模型物理参数的模态识别方法,它利用递归算法对结构进行解耦,只用实测的1个或2个模态数据即可识别结构物理参数. 利用这种方法所识别的物理参数考虑了结构各杆件、各楼层之间的动态耦合效应及柱轴向变形的影响,使简化模型更接近原始模型,从而提高了动力反应的计算精度. 给出了具体工程应用实例.
Abstract:
For lots of structures, a difficult problem in analysis is how to accurately determine the rigidity coefficents and the mass coefficents of the system. In the paper, in order to determine them,we present a parameter identification method with the measurement mode data according to analytical computation of inverse problem in vibration. By means of a recursive algorithm,the physical parameters and inner states of structure can be determined from one or two mode data.The method combine the dynamic coupling efforts and static deformation of the inner states in structure. The simplified system is more accuratelly coincide with the original structue and the calculational accuracy of dynamical reponse is heightened useing the mothed.
