Presently in ground vehicle industries, conducting durability tests with a high acceleration factor have become increasingly demanding for the less time and cost involvement. In the previous work, to accelerate the field test, the standard ‘test tailoring’ approach has been modified due to the requirement of high acceleration factors and the limitations of testing implementation. In this study, a computer-aided testing method is developed for the validation of this modified approach. Hence, a new test-piece has been designed by a conjugative approach involving the finite element technique and fatigue analysis. Afterwards, the accelerated durability loading profiles synthesized via the modified approach have been applied on the designed test-piece and the fatigue life has been simulated to verify the effectiveness of those loading profiles. Simulation results show that loading profiles with an acceleration factor up to 330 can be successfully generated with an accuracy of 95% by this modified approach.
