Abstract

This research focuses on the elastic wave transmission characteristics in an orthotropic plate and isotropic beam coupling system.Based on the dynamic analysis of bending wave propagation, we deduced the power flow transmission coefficient (PTC) formulation between the subsystems and the coupling loss factor (CLF) expression at the coupling boundary.The effects of internal loss factor, frequency and direction angle α on the transmission coefficient were calculated and analyzed.The correctness of the coupled model was verified by comparison with the finite element results.Finally, the coupling structure of the isotropic plate and the beam was compared.Simulation results show that when the bending wave is incident, the direction angle α has significant influence on the transmission coefficient.When the direction angle α is 90°, the transmission coefficient is the smallest.At the same time, the internal loss factor of the beam has significant influence on the transmission coefficient.As the internal loss factor increases, the transmission coefficient also increases.

Key words
