Abstract : Traction behavior of several aerospace fluids and lubricants is correlated to simplified Newtonian models based on viscosity pressure temperature relations. Model coefficients are derived by regression analysis of experimental traction data, which is obtained by a conventional rolling disk type test machine. The model provides fast computation of traction coefficient under prescribed operating conditions and it is well suited for complex computer codes for the dynamic performance simulation of rolling bearings, where the required amount of computer time often imposes severe restrictions on use of the model for practical design.
