[Abstract]:Rare earth giant magnetostrictive transducer is a controllable energy conversion device. It has the characteristics of high conversion efficiency, wide frequency response range, large output amplitude and stable performance. Industrial processing and military sonar are widely used. The rare earth giant magnetostrictive transducer needs to be used in conjunction with the driving power supply. Generally, the drive power supply consists of capacitors, resistors and loads to make up the second-order discharge circuit. When the discharge current reaches the maximum, the switch tube is turned off and the current pulse is generated. The application of Giant Magnetostrictive Transducer is restricted because of its low output power, discontinuous operation and poor range of application. In order to make full use of the performance of the giant magnetic transducer, it is necessary to develop a driving system of the giant magnetic transducer with large output power, strong generality, continuous operation and digital control. In this paper, a kind of drive system of rare earth giant magnetostrictive transducer and the upper computer application program of driving system are developed according to the actual demand, and the driving system is assembled and debugged, and its influence on the output characteristics of the giant magnetic transducer is studied. The main research contents and results are as follows: (1) the hardware circuit of the drive system of rare earth giant magnetostrictive transducer. Firstly, the working state and parameters of the giant magnetostrictive transducer in different environments are designed, and based on this, the overall scheme of the system is determined. The hardware of the driving system consists of three main parts: signal generator. DC power supply and power amplifier module. Then the signal generator is designed based on the direct digital frequency synthesis technology to realize the high precision, digitization and versatility of the output signal of the drive system. In the design of the DC voltage stabilizing circuit, the calculation is carried out according to the working principle of the circuit. The parameters of the main components are obtained. (2) the development of the upper computer application software for the drive system of the rare earth giant magnetostrictive transducer. With the help of LabVIEW software development platform and modularization design principle, the application software of signal generator is developed. The main function is the choice of initial control signal type and the setting of signal parameter attribute. The application software sends out the control signal through the sound card of the upper computer, realizes the control of the hardware circuit, develops the application program, realizes the man-machine interaction of the system, and increases the function of the system.
