Purpose – The present paper aims to experimentally investigate the effect of external horizontal vibration on friction property of an aluminium disc sliding against stainless steel pin.
Design/methodology/approach – To do so, a pin-on-disc apparatus having facility of vibrating the test samples at horizontal direction was designed and fabricated. In the study, a dimensional analysis is done to correlate the friction coefficient of aluminium with sliding velocity, frequency and amplitude of vibration.
Findings – At 100?Hz frequency of vibration, it is seen that during the starting, value of friction coefficient is 0.39 which remains constant for few seconds then increases almost linearly up to 0.45 over a duration of 15?s of rubbing and after that it remains constant for the rest of the experimental time. Similar trends of behavior are observed for transverse vibration. These findings are in agreement with the findings of Chowdhury and Helali.
Originality/value – It is expected that the applications of these results will contribute to the improvement of different concerned mechanical systems.
