To create opportunities for operational control of the parameters of acoustic location devices, it is proposed to make their acoustic screens in the form of electroelastic systems. For devices with cylindrical piezoceramic screens, the method of coupled fields in multi-coupled regions is defined: analytical relations for mechanical fields of location devices, which take into account the mutual connections of electric, mechanical and acoustic fields in the process of energy conversion; acoustic interaction of device elements in the process of forming this energy and mutual connection between these processes. A wide numerical experiment was carried out and its results were analysed in relation to the operational management of the mechanical parameters of location devices. A number of interesting frequency regularities are established, and their physical justification is given. |
