“…It is possible to state that "there is no movement without friction", thus friction always involves vibrations and, therefore, sonic emission [1]. The relative ability of this material to absorb vibration is evaluated as its damping capacity.…”

“…[14][15] or semi-empirical expressions (Eqs. [16][17][18][19] are sufficient to evaluate most of the relevant statistical descriptors of the roughness-induced normal motion. Our results thus further extend the already large range of applicability of EVT to rough contact situations.…”

“…In the following, d 0 (u) is referred to as the normal motion. If the sliding velocity was high enough, the slider could loose contact with the track and enter a bouncing regime ( [15][16][17][18]). In the following, we only consider slow sliding, in which such inertia effects can be neglected.…”

When a rigid rough solid slides on a rigid rough surface, it experiences a random motion in the direction normal to the average contact plane. Here, through simulations of the separation at single-point contact between self-affine topographies, we characterize the statistical and spectral properties of this normal motion. In particular, its rms amplitude is much smaller than that of the equivalent roughness of the two topographies, and depends on the ratio of the slider's lateral size over a characteristic wavelength of the topography. In addition, due to the non-linearity of the sliding contact process, the normal motion's spectrum contains wavelengths smaller than the smallest wavelength present in the underlying topographies. We show that the statistical properties of the normal motion's amplitude are well captured by a simple analytic model based on the extreme value theory framework, extending its applicability to sliding-contact-related topics.

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.
