A Network Of Test Systems And The Application Of Electrical Simulation Of Magnetostrictive Devices

This paper researches and analyses the developments of network measurement systems and magnetostrictive transducers from world wide region. Analyzing the characteristics curve of magnetostrictive transducers based on its equivalent circuit, researching the method how to make sure its syntony frequency and its electric simulation network parameters. Realizing the magnetostrictive transducers network in LabVIEW virtual instrument development environment based on Ethernet. Under Windows NT and LabVIEW development environment, using the linear fit module, exponential fit module > general polynomial fit module of LabVIEW to design a method for fitting the experiment data, the results of curve fitting indicate that the purpose of general polynomial fitting is better than the rest. Separating the equivalent input impedance of magnetostrictive transducers without stimulate current from input impedance of it with stimulate loop based on the results of curve fitting ,and determining the syntony frequency and electric simulation network parameters of magnetostrictive transducers by this input impedance.Finally, with LabVIEW network functions,realizing magnetostrictive transducer electric simulation system based on Web server and discussing a scheme for this system network by DataSocket. The method of this paper can more accurately determine the syntony frequency and electric simulation network parameters of magnetostrictive transducers than the testing method of syntony& anti-syntony.At the same time, discussing virtual instrument measurement system and how to realize magnetostrictive transducer electric simulation network system by LabVIEW network functions of network virtual instrument measurement development environment. The research of this paper and its achievements have some practical merits in the researchful and applied fields of magnetostrictive transducer.
