【摘要】 本文介绍国内外绿色润滑油的发展现状及趋势，主要研究了绿色润滑油基础油和添加剂之间的摩擦作用机理。利用四球机考察了磷酸三丁脂(TBP)和磷酸三苯脂(TPP)作为植物油添加剂的摩擦学性能；应用BP神经网络建立了TPP在菜籽油中的摩擦学模型；用均匀设计组织试验，SAS统计软件分析处理数据，探讨其它添加剂对TBP和TPP在菜籽油中摩擦学性能的影响。结果表明：TBP和TPP能明显改善植物油的抗磨性并有效提高植物油承载能力；用神经网络建立的摩擦学模型能对目标样本进行有效预测，能节省成本；其它添加剂能影响TBP和TPP在菜籽油中摩擦学性能。更多还原

【Abstract】 In this paper the development status and trend of the environmently friendly lubricants at home and abroad are described ,and tribological mechanism between based oils and additives of the the environmently friendly lubricants is mainly studied. The effect of tributyl phosphate (TBP) and TPP as additives on the tribological behabiors of the vegetable oil was studied with a four-ball machine. The tribological model between TPP and rapeseed oil was established by means of BP neutral network. The uniformed design of experiment is used and the SAS of software was adopted to analyze the result in order to discuss that other additives affect the tribological behaviors of TBP and TPP in the rapeseed oil.It has been found that both TBP and TPP as additives increase the load-carrying capacity and antiwear ability of the vegetable oil .And the tribological model can effectively forecasts the results of the objects so it is help to cut the costs.In addition to other additives have the capcity to affect the tribological behaviors of TBP and TPP .更多还原
