Abstract:
In th is paper, a long itudina-l flexural composite mode ultrason ic transducer com po sed o f the sandw ich long itud ina lmode ultrason ic transducer and the flexural regu lar hex agon plate is stud ied. Th is paper adopts FEM ( fin ite e lem ent m ethod) to analyze the patte rn o f the regu lar hexagon p la tesw hich have a certa in g eom etr ic s ize and a free border, and then gets a pattern wh ich has the largest cen tral displacem en t. And then th is paper des igns a long itud ina-l flexura l com posite m ode u ltrasonic transducer w ith the pattern. s frequency as the resonance frequency. The experim ent shows the measured frequency is in ag reement w ith the theoretica l va lues and correspondent w ith the standard of des ign. The transducer designed and produced here is ava ilable for them easurem ent in spec ia l cond itions, and is a lso ava ilab le in super sonic biolog ica l treatm ent and sonochem istry reactor serv ices. W ha t w e have done is bene fic ia l to obta in ing the vibra tion features and the acoustic field d istribution o f the transducer, wh ich are sign ificant for the applica tion.
