摘要
作为半主动控制的执行器,高速开关阀的开、关性能将直接影响半主动控制效果,对其建立准确、可信的模型并进行仿真研究是基于高速开关阀的半主动控制研究的重要环节。本文首先根据磁性材料的磁化曲线建立了高速开关阀非线性数学模型,模型中考虑了磁路中工作气隙的边缘效应及漏磁通;进而设计了试验方案,对该模型进行校验,仿真与试验结果吻合较好;最后,通过试验和仿真对影响高速开关阀性能的一些参数进行分析,并提出相应改善措施。
As the actuator of semi-active control, a high-speed solenoid valve＇s on/off performance will directly influence its control performance. Using the magnetic material＇s magnetization curve, we first build a nonlinear highspeed solenoid valve model taking into account the fringe effect and leakage flux of the main gap in magnetic path. Then the model is verified by the designed experiment. The simulation result agrees with that of the experiment. Finally, by experiment and simulation, we analyze the influence of the parameters of the high-speed solenoid valve and measures for improving the performance are proposed.
