On the principle of energy variation, a stiffness matrix of bar members is here presented, including the influence of shear deformation of the member itself, and taking the nonlinearity and the geometrical nonlinearity of materials into conside- ration. Two kinds of implication of the 《P--Delta》 effect are analyzed. The working condition of the bar member at the elasto plastic stage has been rather comprehensively represented.

On the basis of the principle of energy balance and by means of the concept of substructure, the authors of this paper have conditionally established a set of linear equations concerning the damping parameters of the dynamic model of machine structure. The damping parameters can be immediately obtained by solving the set of equations when other model parameters are known and the value of dynamic stiffness of a certain point on the structure is obtained by testing. The application of this method for identifying the damping parameters is illustrated with practical examples. Because multiple parameters can be identified simultaneously by this method, if experimental conditions are satisfied, it may be expected to identify the damping parameters even when the machine struture is mounted and in the condition of operation.

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。
