This paper researches and analyses the developments of web technology and magnetostrictive transducers from world wide region. the paper also analyes the characteristics curve of magnetostrictive transducers based on its equivalent circuit and researches the method how to make sure its syntony frequency and its electric simulation network parameters. at the same time, by using jsp technology, a magnetostrictive transducer electric simulation application is designed based on b / s three - tier system structure. the experiment data is fitted by curve fitting module. the equivalent input impedance of it with stimulate loop is separated based on the results of curve fitting and the syntony frequency and electric simulation network parameters of magnetostrictive transducers is determined by the input impedance. the method presented in this paper can determine the syntony frequency and electric simulation network parameters of magnetostrictive transducers with a better accuracy than the testing method of syntony & anti - synton y. further more, jsp, the advanced technology at current, has been used to realize a magnetostrictive transducer web electric simulation system. the system has good human computer interface and the function of resource sharing and information publishing. the research of this paper and its achievements have some practical merits in the researchful and applied fields of magnetostrictive transducer
