【摘要】：水的黏度低,潤滑和密封問題突出,水液壓控制閥閥芯上所受的非線性力大,采用傳統(tǒng)的電機(jī)械轉(zhuǎn)換器,性能與油壓元件差距大。音圈電機(jī)體積小,頻響和控制精度高,具有較大輸出力和輸出位移,利用音圈電機(jī)驅(qū)動(dòng)水液壓控制閥,能有效地對(duì)閥芯位移進(jìn)行位置控制。設(shè)計(jì)了具有直線軸承導(dǎo)向和閥芯位移反饋的新型音圈電機(jī)直驅(qū)水液壓節(jié)流控制閥,在音圈電機(jī)數(shù)學(xué)模型和位置控制研究的基礎(chǔ)上,基于AMESim建立了音圈電機(jī)直驅(qū)水液壓節(jié)流控制閥系統(tǒng)仿真模型。仿真與試驗(yàn)結(jié)果表明,控制閥具有較高的線性度和較大的流量調(diào)節(jié)范圍,控制精度高,能夠滿足水液壓傳動(dòng)系統(tǒng)高精度控制的應(yīng)用需求。
[Abstract]:The water viscosity is low, the lubrication and sealing problems are prominent, the nonlinear force on the valve core of the water hydraulic control valve is large, and the performance of the traditional electromechanical converter is far from that of the oil pressure element. The voice coil motor has the advantages of small volume, high frequency response and high control precision, large output force and output displacement. Using the voice coil motor to drive the water hydraulic control valve can effectively control the position of the valve core displacement. A new type of direct drive hydraulic throttle control valve with linear bearing guide and spool displacement feedback is designed. Based on the research of mathematical model and position control of voice coil motor, a new type of hydraulic throttle control valve is designed. The simulation model of hydraulic throttle control valve system for direct drive of voice coil motor is established based on AMESim. The simulation and test results show that the control valve has a high linearity, a large flow regulation range and a high control accuracy, which can meet the application requirements of high precision control of hydraulic transmission system.
