1低摩擦轴向唇形油封的开发显示文摘减小曲轴油封的摩擦力矩可以提高轻型车辆发动机的燃油效率。轻型车辆发动机的曲轴一般采用弹簧径向氟橡胶唇形油封,但是公交车和卡车发动机的曲轴广泛采用轴向硅橡胶唇形油封。轴向机油油封的主唇负荷小、力矩小、可靠性高。在曲轴转动时,轴向唇形油封可持久地保证油封唇和抛油环之间不受污染,因此使用寿命长。将轴向唇形油封应用于轻型车辆发动机,可以实现发动机的低摩擦和高可靠性。在曲轴高速转动时,传统轴向油封的抛油环会有轻微的机油泄漏。为解决该问题,开发了能防止机油泄漏的新型抛油环。实际观察了机油泄漏情况并评估了油封唇对抛油环的跟随性。评估证实,在曲轴高速转动时,油封唇和抛油环之间的间隙相对较小。新开发的轴向唇形油封的摩擦力矩比传统的径向唇形油封小60%。该开发适用于轻型车辆发动机的轴向唇形油封,并具有低摩擦和高可靠性的特点。 高英英(译) 曹杰(译) 2020汽车与新动力2020,3,5:3

8Effect of doped Ni-Bi-B alloy on hydrogen generation performance of Al-InCl3显示文摘In this work,Ni-Bi-B alloy has been synthesized via chemical synthesis method.A new kind of Al-InCl3-(Ni-Bi-B)composite has been prepared by high energy mechanical ball grinding A1 powder with additives.Results show that the doped Ni-Bi-B alloy can significantly improve the hydrogen generation performance of Al-InCl3 and the catalytic activity is enhanced with the increasing content of Bi in Ni-Bi-B alloy.Under optimal conditions,the hydrogen generation yield and conversion yield of Al-InCl3-(Ni-Bi-B)reached1196.8 mL g^-1 and 100.0%at room temperature,respectively.Mechanism study shows five kinds of active sites,such as the fresh surface/defect of Al particle,Al-AlCl3,Al-In,Al-Bi/B and Al-Ni/B produced during the ball milling process.Their synergistic effect enhances the hydrogen generation performance of AlInCl3-(Ni-Bi-B)remarkably.In general,the proposed Al-InCl3-(Ni-Bi-B)composite is possible to serve as hydrogen generation material for fuel cells.Jun Chen F.Xu L.Sun Kexiang Zhang Yongpeng Xia Xiaolei Guo Huanzhi Zhang Fang Yu Erhu Yan Hongliang Peng Pengru Huang Shujun Qiu Cuili Xiang Yujie Sun 2019Journal of Energy Chemistry2019,28,12:1
9Investigation of Optimal Split Ratio of 6-Slot/2-pole High Speed Permanent Magnet Motor with Toroidal Winding显示文摘Split ratio,i.e.the ratio of stator inner diameter to outer diameter,has a closed relationship with electromagnetic performance of permanent magnet(PM)motors.In this paper,the toroidal windings with short end-winding axial length are employed in the 6-slot/2-pole(6s/2p)PM motor for high speed applications.The split ratio is optimized together with the ratio of inner slot to outer slot area,i.e.slot ratio,considering stator total loss(stator iron loss and copper loss).In addition,the influence of maximum stator iron flux density and tooth-tip on the optimal split ratio,slot ratio,and average torque is investigated.The analytical predictions show that when the slot ratio is 0.5,the maximum torque can be achieved,and the optimal split ratio increases with the decrease of slot ratio,as confirmed by the finite element(FE)analyses.Finally,some of predicted results are verified by the measured results of 6s/2p prototype motor with 0.5 slot ratio.F.Xu T.R.He Z.Q.Zhu H.Bin D.Wu L.M.Gong J.T.Chen 2022CES Transactions on Electrical Machines and Systems2022,6,4:0
