Abstract

The invention discloses a hydraulic transmission ultrasonic transducing device, and relates to a transducing device, in particular to the hydraulic transmission ultrasonic transducing device, in order to solve the problems of complex structure, huge size, low energy conversion efficiency and small acoustic power of the conventional transducer. According to the transducing device, a supporting plate, an upper end cover and a lower end cover are sequentially arranged from top to bottom; the lower end cover is connected with the supporting plate through a plurality of pull rods; the upper end cover is connected with the lower end cover through a hydraulic cylinder; the lower surface of the upper end cover, the upper surface of the lower end cover and a cavity of the hydraulic cylinder form a closed cavity; the lower end of a second support pillar penetrates through the supporting plate and the upper end cover from top to bottom in sequence to be arranged in the cavity; the upper end of the second support pillar is connected with the lower end of a first support pillar; a first piston is connected with the lower end of the second support pillar; the outer side wall of the hydraulic cylinder is symmetrically provided with two through holes; a second position is arranged in each through hole, the lower bottom surface of the lower end cover is provided with an oil injection through hole; and the cavity is filled with hydraulic oil. The device is used for the field of mechanical engineering.

Description

technical field [0001] The invention relates to a transducer device, in particular to a hydraulic transmission ultrasonic transducer device. Background technique [0002] In recent years, with the rapid development of new functional materials—rare earth giant magnetostrictive materials (GMM), due to their excellent characteristics such as large magnetostrictive strain, high magnetic-machine coupling coefficient, fast response speed, and high energy density, they have been used in electromechanical Fields show good application prospects. [0003] For this reason, the wide application of fully utilizing the working characteristics of this new type of functional material as an output vibration force and displacement-vibration source (GMA) has attracted a lot of theoretical and analytical research at home and abroad. However, the research on giant magnetostrictive transducers applied to underwater, which converts the axial vibration along the GMM rod generated by the vibration ...
