【摘要】：水的黏度低,润滑和密封问题突出,水液压控制阀阀芯上所受的非线性力大,采用传统的电机械转换器,性能与油压元件差距大。音圈电机体积小,频响和控制精度高,具有较大输出力和输出位移,利用音圈电机驱动水液压控制阀,能有效地对阀芯位移进行位置控制。设计了具有直线轴承导向和阀芯位移反馈的新型音圈电机直驱水液压节流控制阀,在音圈电机数学模型和位置控制研究的基础上,基于AMESim建立了音圈电机直驱水液压节流控制阀系统仿真模型。仿真与试验结果表明,控制阀具有较高的线性度和较大的流量调节范围,控制精度高,能够满足水液压传动系统高精度控制的应用需求。
[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.
