Methods of calculating the inductor ' s quality factor and inductance are studied. experimental results are analyzed in detail and some results are obtained : quality factor q decreasing with the increase of turns n ; inductance l proportional to turns n2 ; series resistance rs increasing - iv - _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ as g - _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ with frequency due to skin effect
得出了一些有用的結論如平面螺旋電感的q值隨著圈數n的增加而減小；電感量與圈數n的平方成正比；高頻時，圈數越多，串聯電阻的趨膚效應越厲害，阻值越大等。 -
The proportional pressure / flow hybrid valve ( pq valve ), which adjusts pressure and flow rate simultaneously, is increasingly adopted for the hydraulic control system in molding machine, due to its advantages of high integration degree, stable and energy - saving performance. based on the analysis of various types of pq valve, this paper investigates the control performance of the byl 16 series valve, including the static and dynamic characteristics
本文在綜合了目前國內外各種pq閥技術現狀的基礎上，分析研究了由浙江大學研製的byl系列pq閥的靜、動態性能，並結合模擬和試驗研究，提出了改善pq閥靜動態性能的機理和有效措施，為今後實際工程應用和系列擴展設計提供了很好的理論依據。 -
