摘要
针对传统磁流变阀流道间隙固定,可控性能差等问题,设计了一种新型流道间隙可调式磁流变阀。采用Ansoft Maxwell电磁场仿真软件对其进行了电磁场仿真,得到了磁感线分布规律以及磁感应强度随路径的变化规律。建立了阀口压降数学模型,并对其进行计算分析,得出了磁流变阀的流量、控制电流、阻尼间隙等参数与压降之间的定量关系。结果表明,当励磁电流为1.5 A、径向流道间隙为0.5 mm时,总压降可达最大值7095 kPa;磁流变阀总压降与电流和流量成正相关,与径向间隙成负相关。研究成果可以为磁流变阀的设计提供一定的理论参考。
Aiming at the problems of traditional magnetorheological(MR)Valve with fixed channel gap and poor controllable performance,a new MR Valve with adjustable channel gap was designed.The magnetic field simulation was conducted using Ansoft Maxwell software,the distribution law of magnetic induction line and the variation law of magnetic induction intensity along the path were obtained.The mathematical model of valve port pressure drop was established and analyzed,and the quantitative relationship between pressure drop and flow rate,current and damping clearance of MR Valve was achieved.The results showed that when the excitation current was 1.5 A and the radial flow gap was 0.5 mm,the total pressure drop could reach the maximum of 7095 kPa.It provides some theoretical reference for the design of MR Valve.
