Numerical simulation and optimization design of acoustic impedance probe

In this article, a set of complete numerical simulation model for the bimorph acoustic impedance probe is developed using finite element method. The resonant characteristics and transmitting-receiving characteristics for the probe are numerically analyzed by ANSYS software. The two sides cover the key steps of the probe research and development. Additionally, the numerical simulation can solve the engineering problems for probe optimization design. An optimized acoustic impedance probe is developed and the measurement is well done. The sample bonding state is distinguished by means of amplitude based method. It has some common reference for probe design and optimization in engineering applications of bonding detection.
