摘　　要：分析了液压系统污染度等级评估标准中存在的不足 ,提出了一种污染度评估的加权灰关联分析方法。该方法克服了实际液压系统中颗粒尺寸分布难以满足原标准 5个尺寸范围规定的不足 ;通过权重的选择 ,综合考虑了实际液压系统的敏感尺寸、液压系统实际运行情况等因素的影响 ,使得污染度等级的评定更具针对性和灵活性。The defect of evaluating standard of oil contamination level for hydraulic system was analyzed. A method of weighting gray relation analysis was presented. The short-coming in original standard that the actual size distribution of pellet can’t satisfy to the given range was resolved by the method. In addition, the sensitive size and the actual condition which influenced the system were concerned by selecting suitable weight .The method was more direct and flexible than that of original standard in oil contamination level evaluation.
