| Abstract: | The model analysis of the design of large platform structure shall not be ignored. An actual example of testing table for impedance of some academy has been studied by use of dynamic finite element program. A primary analysis of the model and harmonic response, were done with an emphasis on its experimental study.The experiment proves that the program of the model should be considered in the design of large platform and the calculation in this paper has a higher accuracy. |
