Investigation on Cable-Beam Vibration by Nonlinear Dynamic FEM
The nonlinear FEM program which name is SD_FEM was developed based on the dynamic integral algorithm by finite element method with considering geometric nonlinearity. A micromesh FEM model was built by this program, the natural vibration characteristic and the vibration response by dynamic loading of the Model was calculated. The conditions of the cable vibration caused by Cable-Beam vibration was discussed when the ratio between global natural frequency of the model and the natural frequency of cable is 1:1, 2:1 or no multiplied. The results of numeric calculation was analyzed, the essential rules of Cable-Beam vibration was summarized.

Abstract：The nonlinear FEM program which name is SD_FEM was developed based on the dynamic integral algorithm by finite element method with considering geometric nonlinearity. A micromesh FEM model was built by this program, the natural vibration characteristic and the vibration response by dynamic loading of the Model was calculated. The conditions of the cable vibration caused by Cable-Beam vibration was discussed when the ratio between global natural frequency of the model and the natural frequency of cable is 1:1, 2:1 or no multiplied. The results of numeric calculation was analyzed, the essential rules of Cable-Beam vibration was summarized.
