AI Technical Summary
Existing technologies make it difficult to accurately obtain load and stress operating data for fan blades, leading to difficulties in predicting the remaining life of fans.
By obtaining the running time of the fan under test under various operating conditions, and using the displacement load spectrum and preset coefficients of the experimental fan, the average value of the fluctuation stress and the average value of the fluctuation amplitude are determined. Combined with the fatigue curve, the unit time life damage value of the fan under test is calculated, thereby predicting its remaining life.
It simplifies the process of predicting the remaining life of the fan, improves the convenience and accuracy of the prediction, and ensures the reliability of the fan in application.
