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 在windowsnt系統(tǒng)環(huán)境和labview虛擬儀器技術(shù)開發(fā)平臺(tái)下,首次利用labview中的直線擬合模塊、指數(shù)擬合模塊以及多項(xiàng)式擬合模塊,設(shè)計(jì)了一種對(duì)實(shí)驗(yàn)所得數(shù)據(jù)進(jìn)行曲線擬合的方法,對(duì)三種擬合方法進(jìn)行了比較,曲線擬合結(jié)果表明,多項(xiàng)式擬合方法相對(duì)于其它兩種擬合方法效果更好;根據(jù)曲線擬合的結(jié)果可從帶激勵(lì)線圈的磁致伸縮換能器的輸入阻抗中分離出磁致伸縮換能器鐵芯在無(wú)激勵(lì)電流時(shí)機(jī)械振動(dòng)形成的等效輸入阻抗,并由此輸入阻抗確定了磁致伸縮換能器的諧振頻率及其電氣模擬網(wǎng)絡(luò)參數(shù);最后通過(guò)labview提供的網(wǎng)絡(luò)功能,實(shí)現(xiàn)了基于web服務(wù)器的磁致伸縮換能器電氣模擬虛擬儀器測(cè)試系統(tǒng),并探討了通過(guò)datasocket技術(shù)實(shí)現(xiàn)該系統(tǒng)網(wǎng)絡(luò)化的方案。
