| Popis: | 94 In this study, based on conceive of Clough, the equation of motion of the Timoshenko beam with the internal viscous damping is derived by using energy principle. Using the Transfer Matrix Method, the characteristic of the system are determined. The cases of the beam with local internal viscous damping are also studied. From the numerical calculation, when the internal viscous damping distributed in the whole beam, the free vibration natural frequency decrease with the damp increase and a critical damping is accordingly appeared. The force vibration response also decreases with the damp. If the damp distributed locally, the characteristic of the system vary with the length and position of the damped section. The optimal location of the damped section, for minimizing the vibration response, is also estimated in present study for a beam. |
