  • Abstract:

    The traditional gear fault detection method does not consider the relationship between gear mechanical fault characteristics and KNN parameters, and optimizes them separately and separately, resulting in low accuracy of gear mechanical fault diagnosis. In this paper, a gear mechanical fault detection model (GA-KNN) with fault characteristics and detection model parameters is proposed. Firstly, the mathematical model of gear mechanical fault detection is constructed by using candidate feature subsets and near-K-parameter parameters, and then the mathematical model is solved by improved genetic algorithm to obtain better accuracy of gear mechanical fault diagnosis. Finally, the performance of the model was tested by simulation experiments. Under the same conditions, compared with the comparison model, the model can obtain the most gear mechanical fault detection model parameters and feature subsets at the same time, which not only improves the mechanical detection accuracy, but also improves the gear mechanical fault detection efficiency.
