“…The highly specialized CFD simulation obtained agrees with the experiment with only insignificant deviations (see Figure 9 on the right side). In addition, the aforementioned simulations with OpenFOAM ® have been validated with respect to lubricant flows in a 32312-A TRB [85][86][87]. Combining the calculated losses from both LaMBDA and CFD simulations, the total bearing losses can be predicted very well (dark blue curve, Figure 9, left).…”

In the presented work, a parametric multibody simulation model is presented that is capable of predicting the friction torque and kinematics of tapered roller bearings. For a highly accurate prediction of bearing friction, consideration of solid and lubricant friction is mandatory. For tapered roller bearings in particular, the friction in the contact between the rolling element and raceway is of importance. Friction forces in the contact between the rolling element end face and inner ring rib as well as roller cage pocket contacts are also considered in the model. A large number of tests were carried out to validate the model in terms of the simulated frictional torque. Influencing variables such as speed, axial load, radial load, and temperature were investigated. The simulation results show good agreement with the measured friction torque, which confirms that the model is well suited to predict frictional torques and therefore the kinematics of tapered roller bearings.
