摘　　要：旨在分析换挡电磁阀的性能对自动变速器换挡平顺性的影响。通过对某大功率液力机械式自动变速器换挡电磁阀工作原理、工作特性的分析,利用AMESim软件建立了仿真模型,研究了主油压、电磁阀电磁力、节流孔直径及阀芯质量等因素对离合器油压的影响,并将蓄能器引入到离合器油路系统中。通过仿真分析可以看出,在离合器油路系统中加入蓄能器可以有效地减小离合器接合过程中的压力波动,以降低换挡冲击,从而提高换挡平顺性。The shift solenoid valve property has a major impact on shifting comfort of automatic transmission. Based on the analysis of solenoid valve working principle for superpower AT, this paper firstly built an AMESim simulation model. And then the paper studied the change in the clutch oil pressure caused by the main oil pressure, electromagnetic force, orifice diameter and spool quality, Finally, the energy accumulator was added into the clutch oil system. The simulation analysis shows that the energy accumulator can effectively reduce oil pressure surge within the clutch engagement process by reducing shift shock while improving shifting comfort.
