摘　　要：电梯运行安全与否直接关系到人们的生命安全。关联维数可以用来识别非线性系统的动态特征,对复杂机械进行故障诊断和监测。研究关联维数在电梯故障诊断中的运用。结果表明:关联维数能够很好地表现电梯的不同工作状况,且关联维数区分度高,可以用于电梯故障特征的提取和电梯工况的监测。The safety of elevator is important to the safety of people＇s life.Correlation dimension can be used to discern the movement characteristics of a non-linear system and to diagnose and monitor the complicated machine.The application of correlation dimension on fault diagnosis of elevator was researched.The results show that correlation dimension can be used to show the different work condition of the elevator,and it has high discrimination.So correlation dimension can be used as a tool to diagnose and monitor the work of the elevator.
