“…[10][11][12][13] Solutions to one-dimensional boundary-value heat conduction problems, describing the process of heating the friction disk and the brake pad, which are made of materials with constant thermophysical properties and temperature-dependent friction coefficient, were obtained in papers. [14][15][16] Analytical-numerical methods for solving one-dimensional thermal problems of friction for thermally sensitive materials with constant coefficient of friction were proposed in papers. [17][18][19][20][21] The aim of this work is to obtain a solution to the thermal problem of friction during braking, with temperature-dependent coefficient of friction for the two half-infinity bodies (the semi-spaces), which are made from thermally sensitive materials.…”

The influence of the thermal sensitivity of a coefficient of friction and thermophysical properties of the pad and disk materials on the temperature distribution during single braking has been studied. For this purpose, the corresponding one-dimensional thermal problem of friction at braking has been formulated. The solution to such nonlinear problem has been made in two stages. First, the partial linearization was carried out using Kirchhoff's substitution, and then, the initial problem for a system of nonlinear ordinary differential equations was obtained by method of lines. Numerical solution to problem was received by Adams' method realized in the DIFSUB package. For a friction pair, disk (steel)-pad (retinax), an analysis of the evolution of sliding speed and temperature was carried out. The results obtained within the model that took into account the mutual influence between the speed and temperature were compared with those obtained without taking into account such effects.

“…However, most often temperatures and stresses are obtained from a solution of a onedimensional contact problem with transient frictional heat generation [10][11][12][13][14][15]. The onedimensional models correspond to those cases when the Peclet number is large and, consequently, the frictional heat flux is normal to the contact surface.…”

ACCEPTED MANUSCRIPT 2 ABSTRACTA two-element model of braking process for a tribosystem consisting of the pad (the strip) sliding with the time-dependent velocity (braking at uniform retardation) on a surface of the disc (the semi-space) is studied. The dependences of temperature and thermal stresses on the boundary conditions on upper surface of the ceramic-metal strip were investigated. It was proved that there is a possibility of applying the obtained results to modelling of a thermal cracking of the frictional elements during braking.

“…The solution to the problem of heat generation during braking with a uniform retardation for two semi-spaces in perfect contact was obtained in articles (Grylytskyy, 1996;Yevtushenko at al., 1999), and in imperfect contact -in articles (Levitskij and Оnyshkievich, 1999;Nosko and Nosko, 2006). The contact temperature, the value of wear, and the speed of sliding during braking, for general experimental dependences of the coefficients of friction and wear on the temperature were studied in article (Olesiak at al., 1997). Solutions to the transient heat conduction problems for a massive body (the semi-space) coated with either a homogeneous, or a composite strip were suggested in articles (Yevtushenko at al., 2007a;Matysiak at al., 2007;Evtushenko at al., 2005).…”
