摘　　要：目前动车组运用检修中使用大量进口油脂,此类油脂都是随整车或部件同步引进,检修单位采购时只能采购指定产品,出现特殊情况时无法保证正常供应,影响动车组正常运用,且进口油脂一般价格较高,影响动车组检修成本。随着检修经验的积累,有针对性地开展油脂国产化研究工作具有现实意义。通过对动车组车门机构工况进行分析,研制了适用于导柱式动车组车门机构使用的润滑脂,替代进口脂开展了国产化行车试验。结果表明国产化润滑脂整体性能稳定,满足运用需求。(图8表4参考文献5)A large amount of imported lubricant greases,typically introduced concurrently with the entire vehicle or its components,are used in the current maintenance processes of Electric Multiple Units(EMUs),and the maintenance department can only procure specified products,leading to supply vulnerabilities in exceptional circumstances and potentially disrupting the normal operation of EMUs.Furthermore,imported lubricating greases generally command higher prices,substantially increasing the maintenance costs of EMUs.With the accumulation of maintenance expertise,conducting targeted research on the localization of lubricants has become increasingly pertinent.A locally developed lubricating grease suitable for guide column-type EMU door mechanisms was successfully developed based on the analysis of the operating conditions of EMU door mechanisms.The field trials which used this lubricating grease as a substitute for imported products demonstrate that the locally developed lubricating grease exhibits consistent overall performance,fully meeting the operational requirements of EMUs(.Charts8 Tables4 References5)
