Abstract

Experiments were conducted to determine the effects of frequency and amplitude of vibration on friction. The experimental analysis also seeks to take into account a variety of factors influencing the coefficient of friction such as normal load and surface roughness. An in-house pin-on-disc apparatus was constructed with a spindle speed control and applied forced-feedback to perform the tests. The response surface methodology is utilized to investigate the effects of the factors and their cross influence on the coefficient of friction for the Steel C1020 and Aluminum 7079. The analysis of variance is done on the experimental data to evaluate the statistical significance of the model. The response equation for the coefficient of friction of Steel C1020 and Aluminum 7079 were determined. The ranges of frequency and amplitude of vibration were 120-600 Hz and 15-225 μm, respectively. Studies have shown that the coefficient of friction decreases with the increase of frequency and amplitude of vibration within the observed ranges for both metals whereas the in case of Aluminum 7079 the coefficient of friction is about 13 % when it compares with the coefficient of friction of Steel C1020.
