Analytical Process and KLT Generation based on a Manual Transmission Dry Clutch System

摘要

This paper presents the development of a model-based methodology, performed at Ford Powertrain Research & Advanced Department for durability prediction and to generate inputs for a Key Life Test (KLT) creation based on an example of a manual transmission dry clutch. Characterization of driving pattern and drive behaviour variation for a manual transmission usage are shown. Development of a dry clutch thermal - and wear model will be explained as important aspects and required inputs to enable durability prediction and to perform attribute trade-offs by model-based iterations. As a result and input to an accelerated KLT results on clutch wear versus driver percentiles are shown for different vehicle pay loads.
