An approach to correlate friction-induced noise with coefficient of friction

In this research study, an attempt has been made to set up a relationship between the frictional noise and friction process parameters to fix the key factors to control the friction-induced noise. The contour interpolation technique and Regression were utilized to correlate frictional noise with the coefficient of friction during the sliding of Steel/Aluminum 4047 alloy and Steel/Alpha Brass alloy tribo-pairs. The effect of surface roughness and frequency was also studied. The results indicate that the range of frictional noise obtained for different testing conditions was 79.56–94.35 dB for Aluminum 4047 alloy and 75.91–90.51 dB for alpha Brass alloy. The results obtained in the present study reveal that sound pressure levels can be mitigated to a good extent provided optimal selection of tribo-parameters.
