Deterioration modeling strategy for pro-active services of commercial vehicles

The goal of deterioration modeling is to support the decision on pro-active replacement of parts in components that have a shorter life cycle than the vehicle (commercial vehicle) itself. A method of deterioration modeling is demonstrated and exemplified at a turbo charger that includes expertise on the components and an integrated mathematical-physical description of wear and takes into account the knowledge on endurance strength. The deterioration model input signals are the load histories of the components which have to be stored in the truck in so called load matrices. For these load matrices a storage space requirement analysis is presented that considers the operation time of the truck and the specific commercial vehicle requirements.
