摘　　要：应用油液监测方法对齿轮箱运行状态进行监测。通过主成分分析的方式测试多特征融合的特性,在充分保留原始特征集信息的条件下确定主成分,实现对齿轮箱状态直接反馈。选择贡献率作为权值,再与各主成分进行相乘并线性相加,获得加权主成分与综合特征组成的融合指标,达到对多特征信息进行加权融合的效果。研究结果表明:主试箱开始运行时指数增长快速,形成剧烈的振动与磨损;之后运行指数表现为高位波动,在油液内形成众多大尺寸磨粒,陪试箱运行指数表现为低处持续增长,保持相对稳定,并未产生剧烈振动;之后陪试箱运行指数快速上升,振动与磨损程度快速提高。Oil monitoring method was adopted to monitor the running state of the gearbox. The characteristics of multi-feature fusion were tested by the method of principal component analysis, and the principal component was determined under the condition of fully retaining the original feature set information to realize the direct feedback to the gearbox state. The contribution rate is selected as the weight value to multiply with each principal component and add linearly, so as to obtain the fusion index composed of weighted principal component and comprehensive feature and achieve the effect of weighted fusion of multi-feature information. The results show that the operating index grows rapidly when the main test box begins to run, causing severe vibration and wear, and as the operating index shows high fluctuation, many large size abrasive particles are formed in the oil. When the operating index of the accompanying test box maintains a low sustained growth with relative satwbility, no violent vibration occurs, while the operating index of the test box grows rapidly, the vibration and wear degree go up fast.
