“…In turn, one of the first researchers who proposed a nonlinear wear model for friction material of brakes was Rhee [10,11]. His groundbreaking work inspired other researchers to conduct further studies of these systems [12,13]. Since then, many mathematical models describing wear processes in friction joints of different type, in different external conditions and for various materials, have come into being yet.…”

Mathematical modeling, theoretical/numerical analysis, and experimental verification of wear processes occurring on the contact surface of friction linings of a mechanical friction clutch are studied. In contrast to many earlier papers we take into consideration wear properties and flexibility of friction materials being in friction contact. During mathematical modeling and numerical simulations we consider a general nonlinear differential model of wear (differential wear model) and a model of wear in the integral form (integral wear model). Equations governing contact pressure and wear distributions of individual friction linings, decrease of distance between clutch shields, and friction torque transmitted by the clutch are derived and compared with experimental data. Both analytical and numerical analyses are carried out with the qualitative and quantitative theories of differential and integral equations, including the Laplace transform approach to ODEs. We show that theoretical results and numerical simulations agree with the experimental data. Finally, a numerical analysis of the proposed mathematical models was carried out in a wider range of parameters of the considered system.

“…For wear of friction material in brake systems, Bajer et al [17] used a very simple wear formula that is a linear function of the local contact pressure. Barecki and Scieszka [16], on the other hand, used almost the same empirical wear formula of Rhee [4] for their winding gear, post-type brake. AbuBakar et al [18] used a modified Rhee's wear formula [4] and assumed all the constants in the formula as unity.…”

“…Instead of verifying wear displacement/intensity/volume as has been adopted by the authors of Refs. [8][9][10][11][12][13][14][15][16], this paper attempts to verify wear progress predicted in the simulation using measured static contact pressure distributions from contact tests and measured surface topography of the friction material. Pressure indicating film and an associated pressure analysis system are used to obtain pressure distributions and magnitude.…”

The Technical University of Silesia is located in Gliwice, some 300 km south-west of Warsaw. Established in 1276, Gliwice is one of a cluster of towns in the relatively small and densely populated (approximately 3.5 million) region of Upper Silesia, which is the industrial heartland of Poland. The Technical University of Silesia was founded in 1945. There are eleven faculties: architecture, electronic, civil, chemical, electrical, mining, environmental, physics, mechanical, materials, and production engineering, with 14,400 full-time engineering students and a teaching staff of about 1,800, including ninety-nine professors.Research and development projects play an important part in the university and reflect the range of courses on offer. The institutes and chairs which form part of every faculty are equipped with research laboratories. These include the Industrial Tribology Laboratory located within the Institute of Mining Mechanisation. The Industrial Tribology Laboratory is active in certain aspects of this interdisciplinary field, notably, the tribology of brake friction materials, tribology in belt conveyors and rope hoists, abrasion and erosion, the contamination and degradation of lubricants, and the performance and reliability of lubricated systems. RESEARCH ACTlVlTlESTribology does not have a long tradition at the Technical University of Silesia, but it is appropriate to mention Professor C. Kajdas and Professor L. Muller, who, in the 1960s and early 1970s, conducted experimental and theoretical work on boundary lubrication, EHD lubrication, wear in gears, and condition monitoring in gear transmissions. Current activities in tribology include:
