| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 87 === This study is based on fraction polynomials to fit curve by using Forsythe Method for the data of frequency response that comes from modal testing. Then, by way of the poles and zeros of fraction polynomials to identify the parameters of dynamic system such as natural frequency, damping ratio and mode shape.
Next, testing the fitting effect on different distribution patterns of frequency response function with fraction polynomials. Moreover, discuss the effect of residual compensation in accordance with choosing the different order of numerator and denominator polynomials. Finally, discuss the issue of Gyroscopic System without regard to damping and test it with the same way.
