If the transducers are all well separated then the design could be done using ideal, non-interacting, point sources, each with the directivity of a single transducer. However in some cases it is required that the array be compact, closely spaced transducers are inevitable, and these will interact through the acoustic medium. Finite\/boundary element modelling techniques naturally take these interactions into account and can thus be used as a design tool even when the system is so complex that intuition is unreliable.<\/p>\n<h3>Features of PAFEC VibroAcoustics for Array Design<\/h3>\n<ul>\n<li>all functionality available for single transducer<\/li>\n<li>mutual impedance computation<\/li>\n<li>axially periodic analysis, for long line arrays<\/li>\n<li>doubly periodic analysis for periodic planar arrays<\/li>\n<li>optimization facility to adjust position automatically<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-532\" src=\"\/wp-content\/uploads\/2017\/08\/DiaAr-09-422x442.gif\" alt=\"\" width=\"422\" height=\"442\" \/><\/p>\n<p style=\"text-align: center;\">Pressure distribution around a diamond array of ring transducers<\/p>\n<p>\u00a0The interaction between transducers can be affected by the level of damping.<\/p>\n<p>Examples:<\/p>\n<ul>\n<li><a href=\".\/index.php\/pafec-vibroacoustics-application-areas\/underwater-acoustics\/array-design\/interaction-effects-of-arrays-of-sonar-transducers\/\">Line array interaction of ring transducers<\/a><\/li>\n<li><a href=\".\/index.php\/pafec-vibroacoustics-application-areas\/underwater-acoustics\/array-design\/cylindrical-array-of-piston-transducers\/\">Cylindrical array of piston transducers<\/a><\/li>\n<li><a href=\".\/index.php\/pafec-vibroacoustics-application-areas\/underwater-acoustics\/array-design\/1-3-composites\/\">1-3 Composites<\/a><\/li>\n<li><a href=\".\/index.php\/pafec-vibroacoustics-application-areas\/underwater-acoustics\/array-design\/radiation-from-a-diamond-array-of-ring-transducers\/\">Diamond array of ring transducers<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Arrays of transducers can be used to produce extra radiated power and directivity.
