Temperature processes at two sliding surfaces subjected to dry friction

Original language description

Application of dry friction damping contact is very often used for damping of turbine blades vibration. This problem is intensively studied in our Institute for several years, but the deficiency of knowledge of special material?s friction characteristicsintroduces serious uncertainty into the results of research, particularly for the friction connection with periodic relative motion. Therefore, laboratory experimental equipment has been designed and realized. Results of the first set of measurement arepresented and discussed. Friction of double steel blade material and overlay of tungsten carbide was investigated for various thrust forces and frequencies of relative motion at the simultaneous measurement of temperatures in three points near the friction surface. An increase of temperature after 25 s of friction run, friction coefficient, friction force, dissipated energy in one cycle during 1 s, entire energy during the friction run, lost power, and energy for 1 oC temperature increa
