Abstract：In order to research on different ratio artificial granite composites modal properties, using orthogonal test method to produce a set of artificial granite composite materials with different ratio,simulated the material model by using finite element analysis software of ANSYS Workbench, and to confirming the simulation,under the help of Multi channel dynamic signal analysis system, a series of modal tests is made.By analyzing the results, it is found that the natural frequency and damping ratio are affected by the artificial granite materials.The following conclusions: (1) Simulation and experimental modal natural frequency obtained the same trend, the same modes;(2) Epoxy resin and aggregate grade have great influence on material damping;(3) Aggregate gradation and curing agent has little effect on the natural frequency, epoxy resins and diluents amount greater impact.
