Untimely machinery breakdown will incur significant losses, especially to the manufacturing company as it affects the production rates. During operation, machines generate vibrations and there are unwanted vibrations that will disrupt the machine system, which results in faults such as imbalance, wear, and misalignment. Thus, vibration analysis has become an effective method to monitor the ...

This work proposes a fault detection system of rotating machines using vibration signal analysis. First, a dataset of 3dimensional vibration signals is acquired from large induction motors representing healthy and faulty states. The signal conditioning is performed using empirical mode decomposition technique.

The dynamic characteristics in a rolling process have been investigated with various methods, but a mathematical model to predict actual chatter vibration has not been established. In this paper, we propose a mathematical model of a cold rolling mill to predict chatter vibration. The mathematical model was verified by experiment and theoretical analysis. The chatter frequency predicted by the ...
