Summary:

Durability is one of the most important goals in the currentstate-of the-art design of new vehicles. Usually the durabilityperformance is validated by the vehicle manufacturers drivingdirectly the prototypes in field or through endurance schedules onproving ground fatigue surfaces. The validation procedure drivingdirectly in field is very expensive and time-consuming. Thereliability and accuracy of validations in proving ground surfacesare many times unknown, mainly because such endurance schedules arenot fitted to the market (driving conditions and type of roads) andhistorically are based on empirical procedures.This paper discusses how IDIADA has developed a methodology todesign accelerated durability schedules which obtain less expensiveand fast durability validation procedures, as well as beingreliable and fitted to the market and durability targets.The development of the methodology is based on the analysis andextrapolation of the information collected directly in market (RoadLoad Data) in order to design endurance schedules using theaccelerated fatigue surfaces of the proving grounds
