Simulative investigations on different friction coefficient models

摘要

This work aims on the comparison of different friction coefficient models depending on the variable parameters including sliding speed, temperature, contact pressure based on experimental friction measurements. The impact on the temperature distribution to predict phase transformations during turning of AISI 4140 for dry and minimum quantity lubricated machining is investigated for each parameter separately. Based on these results an optimized friction model is built up. The results are validated with experiments.
