Effects of boundary conditions on vibrating mode of acoustic logging dipole transducer

Abstract

Acoustic transducer is an important part of acoustic well logging tool. In this paper, ANSYS software package is used to design acoustic dipole transducer and simulate vibrating mode of the dipole transducer in different mechanical boundary conditions. The results show that boundary conditions influence the number of vibrating mode in the same frequency band and the frequency value of the same vibrating mode. Several acoustic dipole transducers are designed according to the results of numerical simulation and laboratory measurements. The basic frequency of vibrating mode of experiment has good agreement with that of simulation. The numerical simulation plays a good guidance role in designing, producing and correctly installing the acoustic dipole transducer.acoustic dipole transducer, vibrating mode, basic frequency, acoustic well logging
