The dial has to be suitable for the demonstration of the inductive current from the slow input and output rodlike magnet in coil of 300 spirals 刻度線必須適合來(lái)演示在300圈螺旋線圈中慢慢抽進(jìn)抽出的棒壯磁條所產(chǎn)生的感應(yīng)電流。
The simulation results indicate that the two circuits " currents have the same frequency and the inductive current is at the same quantity class as the discharging current Ansys仿真的結(jié)果表明:兩個(gè)回路的電流的頻率相同,感應(yīng)回路的電流強(qiáng)度非常大,與初級(jí)回路處于同一數(shù)量級(jí),只是落后一個(gè)相位角。
First , the conducting targets ' electromagnetic scattering is researched in this paper . the rwg vector base functions are used to denote inductive current on the surface of the conducting target . efie is built . the rcs of conducting sphere . conducting plate , conducting cube are calculated respectively , the electromagnetic scattering of multi - rivets on the conducting plate are researched the first time , and the impaction of multi - rivets to the total rcs is analyzed 用rwg矢量基函數(shù)表示導(dǎo)體表面的感應(yīng)電流,建立了導(dǎo)體表面的電場(chǎng)積分方程( efie ) ,分別計(jì)算了導(dǎo)電球、導(dǎo)體平板、導(dǎo)電立方體的rcs ,首次研究了導(dǎo)電平板上有多個(gè)鉚釘?shù)碾姶派⑸?,分析了多個(gè)鉚釘對(duì)目標(biāo)總的rcs的影響。
The new instrument add a sensor that can gather the signal of the stator inductive current . and by analyzing the signal of the stator inductive current , judge the moving state of the electromotor . this instrument is mainly diagnosis the follow fault : the fragment of the bar in the rotor fault , the fault of eccentricity of the interspace between the rotor and the state of the electromotor . , 本儀器是在回轉(zhuǎn)機(jī)械故障診斷與監(jiān)測(cè)系統(tǒng)的基礎(chǔ)上開發(fā)的,同時(shí),根據(jù)電機(jī)這種特殊設(shè)備的實(shí)際情況,增加了電機(jī)電氣信號(hào)的檢測(cè),即通過對(duì)電機(jī)定子三項(xiàng)繞組電流信號(hào)的變化分析,來(lái)找出電機(jī)的電氣故障,主要是轉(zhuǎn)子斷條,氣隙偏心故障以及定子等故障。
From the model , we can solve and gain the values and change orders of charging current , charging voltage , discharging current , discharging voltage and inductive current . after that , the electromagnetic fields can be created from two circuits " currents , and their magnetic rector and flux can be simulated from ansys solver 用ansys multiphysics模塊求解出充電電流、充電電壓、放電電流、放電電壓和感應(yīng)電流以及這些參數(shù)隨時(shí)間變化的規(guī)律:然后利用兩個(gè)回路的電流耦合出電磁場(chǎng),并仿真出磁矢量、磁通密度。
