IMPACT OF MEASUREMENT UNCERTAINTIES ON THE VALIDATION OF MIXED LUBRICATION SIMULATION

摘要

This contribution shows the application of methods of the uncertainty quantification on the validation of mixed lubrication simulation. The final result is the comparison between experiment and simulation shown in Fig. 7. The uncertainty of the computed friction due to measurement uncertainties of simulation inputs is higher than the uncertainty of the measured friction. A probabilistic comparison between experiment and simulation is required to assess the validity. The results also indicate that simulation input uncertainties have to be considered in further model improvement which uses even more input parameters derived from experiments.
