摘要
电磁阀作为汽车空调压缩机实现排量调节的关键执行元件,其性能分析和结构优化有利于优化压缩机的排量控制。基于有限元分析法,建立电磁阀结构模型,探究电磁阀中的线圈结构、线圈匝数、输电电压等参数对电磁阀的响应时间、吸合时间、电磁力等特性的影响。结果表明,在相同条件下,T字形线圈结构的电磁力大于圆柱形线圈,可扩大电磁阀的使用范围。激励电压从4 V增加到12 V,T字形线圈的电磁力呈递增趋势,受力均匀性优于圆柱形线圈结构。线圈匝数与动静铁芯的吸合时间、吸合力呈正相关。
As the key actuator of the output volume monitor of the automobile air conditioning compressor,the performance analysis and structure optimization are helpful to optimize the displacement control of compressor.This paper aims to establish a structure model of solenoid valve to investigate the influence of the parameters such as coil structure,coil turns,transmission voltage at al.On the response time,pull-in time,electromagnetic force and other characteristics of solenoid valve.The results show that the electromagnetic force of the T-type coil is greater than that of the cylindrical coil under the same conditions,which can enlarge the application range of solenoid valve.When the excitation voltage increases from 4 V to 12 V,the electromagnetic force of T-type coil increases gradually,and the force uniformity is better than that of cylindrical coil.The number of turns is positively correlated with the pull-in time and pull-in force of the static magnetic core.
