EXPERIMENTAL VERIFICATION OF THE EFFICIENCY OF THERMAL DIAGNOSTICS OF FRICTION IN A SYSTEM OF SLIDING BEARINGS AT LOW SHAFT SPEEDS

To assess the effi ciency of the method of thermal diagnostics of friction in a system of sliding bearings at shaft speeds of no more than 2π rad/s, friction torque values obtained by solving an inverse heat-transfer problem and measuring with a commercial friction machine sensor have been compared. It has been established that the agreement between the total friction torque values obtained using fundamentally different methods is within 10–15%. The ability of the thermal diagnostics method to identify differing friction torques in each bearing is substantiated by the recovery of their identical values under conditions of difference of the temperature fi elds in the bearings
