Transducer characteristics and calibration methodsA hydroacoustic transducer is a device that converts acoustic energy and electrical energy each other. The position in sonar is similar to the antenna in a radio, an acoustic system that emits and receives sound waves in seawater. A piezoelectric tra

Combined with piezoelectric plane strain and three-dimensional piezoelasticity theory, the vibration characteristics of a piezoelectric ceramic thick hollow cylinder with radial polarization has been studied, and closed-type solutions are obtained for the mechanical radial displacement and electric

The comparison test between A120 ordinary grinding and ultrasonic grinding was carried out under the different vibration modes. The primary and secondary order of the influence of various grinding process parameters on the surface roughness of the workpiece was studied, and the workpiece rotation sp

Alumina acoustic piezoelectric tubes materials are difficult to process materials, with the high hardness, brittleness including grinding, cutting, laser heating, high pressure abrasive water processing and ultrasonic processing. Grinding: Alumina piezo ceramics have the high hardness, so gr
