Abstract:Using finite element methods to carry on the numerical simulation, from which getting all steps natural frequency of the complex plywood. The experiment research is carried on by using the experimental modal analysis, from which all steps natural frequency and damping are got. In addition, compare with all steps of natural frequency and damping between the single layers of sheet metal and complex plywood. It is showed that the complex plywood has good characteristic of reducing shake and resisting noise.
Keywords:complex plywood  modal analysis  dynamic characteristic  reducing vibration and resisting noise
