“…Other than that, the temperature rise in the contact area can also be calculated either by the analytical method [13][14][15][16][17] or by the numerical method [18][19][20][21][22][23].…”

“…Lunden [23] proposed a 2D thermo-elastic-plastic finite element model (FE) to study the plastic stresses and strains in the contact area of the wheel. Spiryagin et al [22] recommended a mathematical model to calculate the temperature in the wheel-rail flange contact to detect the lubricant type at this contact location. Numerical algorithm was applied by Chudzikiewicz et al [21] to build up a thermoelastic model with elastic graded materials to investigate the frictional heat generation and heat transfer across the contact surface.…”

“…For example, when a rail vehicle is running around a curve, especially a tight curve, both the sliding velocity and the pressure are so high that they can cause flash temperatures higher than 500ºC [12,13]. This temperature will be several times higher in a flange contact [12,13].…”

“…This temperature will be several times higher in a flange contact [12,13]. As a result, the flash temperature in the flange contact in a high rail or the contact for locomotives can easily exceed 100ºC, vaporizing the water in the friction modifier and increasing the replacement rate needed to keep the same functionality.…”

Knowledge of wheel-rail interaction is crucial to wheel and rail maintenance. In this interaction, some of the worn-off material is transformed into airborne particles. Although such wear is well understood, few studies treat the particles generated. We investigated friction modifiers' effects on airborne particles characteristics generated in wheel-rail contacts in laboratory conditions. Pin-on-disc machine testing with a round-head pin loaded by a dead weight load 40 N simulated maximum contact pressure over 550 MPa. Airborne particle characteristics were investigated in dry contacts and in ones lubricated with biodegradable rail grease and water-and oil-based friction modifiers. The number of particles declined with the grease; the number of ultrafine particles increased with the water-based friction modifier, mainly due to water vaporization.

“…Wear between the wheel and the rail is a complex phenomenon that depends on many factors. One of the main areas in which there is a process of wear and tear is in the lateral contact between the wheel and rail flange (wheel-rail flange contact) [6]. Due to wear, heat is generated in two different places between the wheel and the rail head and between a rail flange of the wheel when the train moves.…”

Preliminary communicationThis paper presents a mathematical model for the prediction of the thermal behaviour of a cylindrical roller bearing for axle assembly of the wheel set of the towed railway vehicles. The mathematical model allows for the heat generated due to lubrication, radial and axial loads at different speeds of the train to be calculated. The method of calculating of the heat conducting and converting coefficients in the bearing is also shown. By using the general purpose software system based on the finite elements method, the thermal behaviour of the above mentioned cylindrical roller bearings was analysed. Temperature values of the bearings are determined by the finite elements method values depending on the speed of the train movement on a straight-line section and the curve (v = 20 km/h, v = 40 km/h, v = 60 km/h, v = 80 km/h and v = 100 km/h), the curve radius (R = 500 m), the ambient temperature of 20 °C and the cant height (h = 110 mm, h = 140 mm, h = 180 mm). Keywords: cylindrical roller bearing for towed railway vehicles; finite elements method; mathematical modelling Matematičko modeliranje toplinskog ponašanja valjnog ležaja s valjčićima za vučena željeznička vozilaPrethodno priopćemje U radu je prikazan matematički model za predviđanje toplinskog ponašanja valjnog ležaja s valjčićima za uležištenje vučenih željezničkih vozila. Matematički model omogućava izračunavanje generirane topline uslijed podmazivanja, radijalnog i aksijalnog opterećenja za različite brzine gibanja vlaka. U radu je također prikazan način izračunavanja koeficijenata provođenja i prevođenja topline u ležaju. Uporabom programskog sustava opće namjene na bazi metode konačnih elemenata analizirano je toplinsko ponašanje valjnog ležaja s valjčićima za vučena željeznička vozila. Metodom konačnih elemenata određene su vrijednosti temperature ležaja u ovisnosti o brzini gibanja vlaka (v = 20 km/h, v = 40 km/h, v = 60 km/h, v = 80 km/h i v = 100 km/h), polumjera zakrivljenosti zavoja (R = 500 m), ambijentalne temperature od 20 °C i visine nadvišenja pruge u krivini (h = 110 mm, h = 140 mm, h = 180 mm).
