Abstract

In this paper, a new simulation method for the transducer acoustics field in multilayer irregular media boundaries is presented. Based on the acoustic wave vibration equation, Snell's law, other physical models, and finite element methods, this study uses the method by overlapping the media space model and the boundary surface model to solve the problem of simulating the transducer acoustics field in multilayer irregular media boundaries and reduces the computational redundancy. The simulation software uses a point drawing algorithm and OpenGL to generate the 3D image of the media space model. The simulation system achieves the simulation of the transient state acoustic field at any moment and analysis the effect of any point source at the focal plane by saving the virtual point source's vibration equation at each sampling point. In addition, this study demonstrates the feasibility of the simulation method by comparing the simulation results with the real measurement result of acoustic pressure distribution.
