本文以能量平衡原理为基础,借用子结构概念,有条件地建立了以动态模型的阻尼参数为未知数的线性方程组,在已知其他模型参数并实测得到结构上某点的动刚度值的前提下,由解方程组可直接得到各阻尼参数的值。运用实例,说明了本文方法的应用。由于使用方法可以同时识别多个阻尼参数,所以在实验条件能够满足的情况下,可望在结构的实际安装和工作状态下进行阻尼参数的识别。 Based on the principle of energy balance, using the concept of substructure, this paper establishes conditionally the linear equations with damping parameters of dynamic model as unknown. The premise of knowing the parameters of other models and measuring the dynamic stiffness value of a certain point on the structure is obtained. Next, the values ​​of the damping parameters can be directly obtained from the solution equations. Examples are used to illustrate the application of this method. Because the use method can identify multiple damping parameters at the same time, it is expected that the damping parameters can be identified in the actual installation and working state of the structure under the condition that the experimental conditions can be satisfied.
