摘　　要：齿轮箱运行状况的优劣是整个设备平稳运行的基础保障,因而对齿轮箱运行状态监测和综合评价具有显著的意义。针对传统状态评价方法中指标权重确定的局限性,创造性地引入了熵值修正G1模型对评价指标进行科学合理地赋权,同时提出相对健康度概念,并用不同的健康等级来定量描述齿轮箱的运行状态,建立了基于相对健康度的评价模型。通过对某石化公司齿轮箱故障的分析表明,该方法能够有效地判断齿轮箱的运行状态,为视情维修提供理论依据。Since the state of operational performance of gearbox proper on the guarantee for smooth of entire device,it is quite significant to monitor and evaluate comprehensively its state of operation.Owing to the limitations of index weight determination in traditional state evaluation method,the entropy model modified G1 is innovatively introduced to scientific and reasonable weight,the concept of relative health degree is proposed,and the grades of health state are classified based on the healthy values to quantitatively describe the running state of gearbox.The analysis of the gearbox fault in certain petrochemical company shows that,this method has better effective in evaluating the gearbox running status,it can provide a theoretical basis for the maintenance based on state.
