Effect of Surface Roughness Combination on Frictional Sound Tohoku University * Boyko Stoimenov
Introduction Whenever two bodies slide against each other in dry contact, they start to vibrate and radiate sound. It is believed that the main cause for such small-scale vibration and sound is thesurface roughness. Despite this common recognition, there are only a small number of past experimental studies focused on the effect of surface roughness on friction induced sound. Takahashi  studied frictional noise under heavy load, generated by the contact of the rim of a rotating cylinder against a plate specimen (Rmax
