Fan Fault Diagnosis System Based on Virtual Prototyping Technology

One fault diagnosis system is proposed to monitor the fan system condition based on virtual prototyping technology. According to the real fan system structure and its foundation condition, the three-dimensional model is built. Under virtual environment, the components are assembled, and the constraints and driver are added. After validate the model, the typical mechanical faults of fans (unbalance, misalignment etc.) are simulated. By virtual sensors, the acquired fan data are used to establish the corresponding fan condition database. The real fan condition can be identified through comparing measured signal with virtual data. Pattern recognition and early prediction are feasible for dynamic operation of the equipment during the process of incipient fault. The contribution of this paper is to propose a new approach to equipment maintenance that makes the maintenance process "low consumption and high efficiency".
