| 摘 要： | 建立了高频电气喷射阀电磁铁的有限元分析模型.在静态有限元分析基础上,通过减小喷射阀衔铁外径及在其中心钻孔对电磁铁结构进行了优化设计.优化后模型的结构尺寸及提供的稳态电磁力均与优化前相当,而衔铁质量下降71%,故其加速度大幅上升,使得优化后模型的动态响应时间在各工作状况下均约缩短8%.最后,根据优化后电磁铁模型加工制造了电气喷射阀样机,并研制了其动态性能测试系统.试验与仿真结果吻合,验证了仿真模型的有效性.

| Abstract: | A finite element simulation model of the high-speed electro-pneumatic ejector valve actuator was built to analyze its steady state and transient performances. Optimal design was implemented by turning the fringe part and boring the center part of the armature base on steady state finite element analysis.Comparing with the original actuator,the optimized actuator has an almost 71% reducing in the armature weight whilst without significant steady state solenoid force loss in the actuator and without significa... |
