| Abstract: | In this paper, the suspended structure has been simplified to the series-parallel-connection model. The consistent-stiffness matrix and consistent-mass matrix also have been established which considered joint rotation. After predigesting the stiffness matrix and mass matrix, the vertical stiffness matrix and mass matrix have been obtained. There has been vertical vibrational mode analysis on the model, From the result of analysis some characters and conclusions of suspended structure under vertical vibration have been obtained. |
