| Abstract: | In this paper,a Z-F method of identifying complex modal parameters for large and cornpliated mechanical structures is developed.With this method,the distortion in the curve fitting not only can be avoided,but also the high accurate result can be approached in case of crowded modes.It was applied to the structural dynamicanalysis of the S7512 thread grinder with satisfactory results. |

| Keywords: | dynamic characteristic curve fitting identification of modal parameter |
