摘要：
A numerical-experimental study of the displacements distribution and the radiated field of various (directional and focusing) flexural plate transducers is presented. The numerical method basically consists of calculating the distribution of displacements of the transducers by the finite element method by using the code ATILA while the corresponding radiated field is calculated by the boundary element method by means of the code EQI. In this way the near and far field of the transducers is calculated as well as their directivity pattern and vibration distribution. The obtained results are compared with experimental data. The good agreement obtained indicates that the numerical method used in this paper is a very useful tool for calculating the field of transducers and for the optimisation of their design.
