| Abstract: | The authors outline the basic principles of dynamic substructure method for calculating the modal parameters of complex system. In order to determine the reasonable discrete mathematical model for the generator structure, by adopting the technique combining finite element method with test model analysis the dynamic characteristics are analysed of the organic glass structural model for the main components in the generator. On the basis of this discrete model, the dynamic characteristic of the prototype of the generator structure is studied thus verifying the reliability of this generator structure designed. |
