ABSTRACT:
A block cycle of stress-inducing test conditions is repeatedly applied to a vehicle part (302) on a test stand (266). The number of applications of the block cycle is predetermined such that the cumulative test conditions applied to the vehicle part (302) correspond to actual driving conditions previously experienced by one or more prototype vehicle parts (200) throughout a predetermined number of driven miles. When the repetitive block cycles have been completed, the vehicle part (302) is inspected to determine an induced degree of deterioration corresponding to the predetermined number of driven miles. The induced degree of deterioration forecasts actual deterioration expected for a plurality of duplicate vehicle parts under actual driving conditions in vehicles driven the same number of miles.
