| 摘 要： | 通过实验获取了6160A柴油机在正常情况及几种故障情况下的扭矩信号,利用小波及混沌方法进行分析,对各信号进行相空间重构,并计算其关联维数及K熵。计算结果显示,柴油机在不同工作状态时,其扭矩及转速信号的关联维数及K熵各不相同。

| Abstract: | Torque signals are obtained from experiment on 6160A diesel engine in normal condition and faulty condition. Wavelet packet method and chaos method are used to phase-space reconstruct torque signals and calculate the relevant dimension and K entropy. The result of calculation shows that the relevant dimension and K entropy of torque and speed signals are different in varied operating condition. |
