Optimisation of the process of experimental sign off of a vehicle

This paper describes the designing process of durability sign off tests for new vehicles. The reliability tests must be based on experimental measures performed on physical prototype, subjected to tests on public roads. These data, translated into Rainflow domain, will be used to statistically define the target. Then the prototype is tested on test tracks so that a particular combination of them can be selected to define a sequence that can match the target. An IVECO vehicle will be presented as test-case. This activity is an outcome of the cooperation between the Industrial Engineering Department at the Perugia University and IVECO Testing Labs and Methodologies of Turin.
