“…They used a pin sliding on a rim to investigate various aspects of friction sound, including the effects of rim roughness on the generated sound. Stoimenov et al [10,11] revealed that the peak frequency of friction sound generated by rubbing two flat rough surfaces together is determined by the roughness at the contact interface. The peak frequency shifts to a higher frequency when the contact becomes smoother.…”

Among the phenomena that occur as a result of contact between two surfaces is friction sound, in which surface roughness is of great importance. In this study, the parameter of contact stiffness is used to explain the frequency characteristic of vibration generated by the rubbing of flat surfaces under a small load. A 3-disk configuration rubbing method was used, which provides a unique characteristic of the system's frequency response function containing specific information about the rubbing vibrations. It is shown that the peak frequency of the rubbing vibration can be explained by using a two-degrees-of-freedom model incorporating the parameter of contact stiffness. A quantitative relationship between the surface roughness and the peak frequency of the rubbing vibrations was established. AbstrakAnalisis Getaran yang Terjadi pada Usapan Permukaan Rata. Bunyi gesekan adalah salah satu fenomena yang terjadi akibat interaksi kontak antara dua permukaan yang dipengaruhi oleh faktor kekasaran permukaan. Dalam kajian ini, parameter kekakuan kontak dipakai untuk menjelaskan karakteristik getaran yang terjadi pada saat sebuah permukaan diusapkan pada sebuah permukaan yang lain dalam kondisi beban yang kecil. Metode usapan konfigurasi 3 (tiga) cakram digunakan dalam kajian ini, yang menghasilkan respon frekuensi yang unik yang mengandung informasi karakteristik dinamik sistem. Frekuensi puncak getaran yang diakibatkan oleh usapan dapat dijelaskan dengan menggunakan model dinamik dua derajat kebebasan yang mengandung parameter kekakuan kontak. Pada kajian ini, suatu hubungan kuantitatif antara kekasaran permukaan dan frekuensi puncak getaran usapan telah dihasilkan.

“…They are often included in general studies on friction noise where it is sometimes difficult to separate steady sliding and stick-slip regimes. Let quote the work of Yokoi and Nakai [23], Othman et al [24], Stoimenov et al [25], and Ben Abdelounis et al [26] who have studied the link between the sound pressure level and roughness and sliding speed. They propose a power law P a / Ra a V b where P a is the acoustical radiated power, V the sliding speed and Ra a roughness parameter.…”

International audienceThe relationship which links the normal vibration occuring during the sliding of rough surfaces and the nominal contact area is investigated. Two regimes are found. In the ﬁrst one, the vibrational level does not depend on the contact area while in the second one, it is proportional to the contact area. A theoretical model is proposed. It is based on the assumption that the vibrational level results from a competition between two processes of vibration damping, the internal damping of the material and the contact damping occuring at the interface

“…They clarify the dependence of roughness noise with roughness and sliding speed. Othman et al [7,8] studied the contact between a stylus and a rough surface, Yokoi and Nakai [9] did the experiment with a rod-disk contact and the plane-plane contact has been tackled by Kato et al [10], Stoimenov et al [11], and Ben Abdelounis et al [12]. Although all these experimental setups are quite different and therefore several sliding regimes are covered, it seems that there is an agreement around a power law,…”

This study presents an experiment to measure the dependence of friction noise versus the nominal contact area. The friction-induced vibration is generated by the sliding of two rough surfaces. The normal load is low leading to a weak contact. The normal load and the sliding velocity are maintained constant. The nominal contact area ranges over two orders of magnitude. It is found that two regimes exist. On the one hand, the vibration energy is proportional to the contact area. But on the second hand, the vibration energy is constant, i.e., does not depend on the contact area.
