集成式电磁阀设计及阀芯卡滞优化

采用一维软件进行电磁阀参数设计，利用3D制图软件进行建模，使用三维流体软件进行功能校核及优化，设计集成式电磁阀。针对电磁阀卡滞问题，应用CFD方法计算阀芯特定工作位置下的稳态液动力和全工况瞬态液动力；对比轴向液动力、弹簧力与电磁力的平衡关系，校核径向液动力大小，排查设计缺陷，筛选关键参数，进行导向性优化设计。结果表明：增加阀芯槽深或在阀芯出口位置增加坡角设计，能够有效解决电磁阀阀芯卡滞问题。

Integrated Solenoid Design and Stuck Issue Optimization

A solenoid valve parameters were designed by using 1D software, a 3D drawing software was used to generate parameter model, and a 3D fluid software was used to verify and optimization the valve performance. Focus on solenoid stuck problem, CFD method was used to calculate spool steady fluid force on special working point and dynamic fluid force during movement process; force balance relationship between spool axial fluid force, spring force and magnet force was compared, spool radial fluid force was verified, the design defects were checked, key parameters were selected, and the guiding design was optimized. The results show that increase spool groove depth or add slope angle at outlet position, the solenoid spool struck issue can be solvee efficiently.
