For the problem of honeycomb sandwich vibration, the inherent frequencies and modal shapes of sample plate of 65002 overlay were measured to analyze the vibration characteristic, the elastic modulus of core layer and surface layer were adversely deduced by establishing finite element model and using the method of ANSYS circulating search. Modal shapes and inherent frequencies of the honeycomb sandwich were calculated by using the elastic modulus. Comparison with experimental results verifies the reliability of ANSYS circulating search. Results show that modal shapes coincide well with test with an error less than 2.0%, which verifies the reliability of ANSYS circulating search, and then provides basis to study the vibration of yacht honeycomb sandwich by using the finite element simulation.
