摘要
以润滑油的理化性能指标为基础,分析了油液性能衰变的本质原因及对发动机磨损的影响,结合某特种车工作环境的特点,建立了车用发动机润滑油性能评估指标体系。定性分析了评估指标,确定了指标的权重,建立了润滑油的模糊评价模型,并结合实例验证了该评估体系的合理性与准确性。该研究对特种车发动机润滑油性能的及时改善和按质换油具有一定的指导意义。
Based on the physical and chemical performance of lubricant,the nature of lubricant decay and its influence on engine wear was analyzed.Then the evaluation index system of lubricant property was established according to the working environment of a special vehicle.The evaluation index was qualitatively analyzed,the weight of index was determined,the fuzzy evaluation model was built and finally the effectiveness and accuracy of the model was verified by the actual example.The research will make a contribution to lubricant property improvement and in time changing of special vehicle.
