| Abstract: | The working principle of multi point sine excitation system is simply introduced.Through the dynamic property model test for Wan'an Project's guide wall,the installation of exciter and test method for oscillating mode are studied.The relative solvable methods on easily appearing effects of disadvantageous factors are proposed.And the modal parameters of self oscillation frequency,vibration mode and damp are precisely found. |
| Keywords: | multi point excitation system exciting force acceleration mode test |
