| Summary: | 碩士 === 國立虎尾科技大學 === 航空與電子科技研究所 === 103 === The research explores spring constant, damping coefficient and mass of damper parameter analysis of a structure of stack carrying a TDMD with arbitrary magnitudes were made by means of the analytical and numerical combined method (ANCM) and finite element method(FEM).
The analysis of results in ANCM, the TDMD installs the location by the fixed port more approach free port, the natural frequency changes more big, gradually increase to the spring constant value, it the first natural frequency also gradually enlarge, but the second and the third natural frequency all have no change, camping coefficient value gradually increases, it the value decrement of first natural frequency is small, but the second and the third natural frequency all have no change, the analysis of results in FEM, spring constant, camping coefficient and mass magnitudes to its first, the second with the trend of third natural frequencies change trend with corresponding one obtained from analytical and numerical combined method.
