| Abstract: | The theory of similitude for designing the model of the combined blown converter and the method for determining the dominant frequency bands and the vibration shape of the system, and for identifying the dynamic characteristics of the system are presented in this paper. It is found that the system is subjected to the low-frequency excitation and occurs random vibration in the non-linear complex-mode form. These results have important values for the practical use of com bined blown technique and the design of the converter authors have cold-state vibration testes of a model of the large-scale. |
