Summary:

For many years durability tests engineers have worked in thesense of improving the tests that, at first, were performed usingpublic roads with high time consumption and low reproducibility.Proving grounds were specially designed to reproduce the mostimportant efforts to the body and chassis systems, but time problemwas still there.Time and cost reduction allied to the needs of quality,reliability and reproducibility improvement led the engineers todevelop methods and equipments to reproduce the durability tests inthe lab. In this way the road simulators appear as a powerful toolable to perform durability tests with high reliability,self-controlled and with very low time compared to the road tests.At this scenery bench tests were also created to components andsystems mainly used to anticipate problems before a whole vehicletest.A greater number of bench tests are performed using constantamplitude sinusoidal signals based on a statistical study ofefforts on a component or system covering the related variables.However, at the real world, loads come into the vehicle through thesuspension not following any sequence and are present in a randomform varying from tension to compression with infinity ofamplitudes, frequency and cycle average values. Bench testsimprovement pass through to put in consideration the inherentrandom phenomenon. Besides, bench tests must be damage equivalentand be able to reproduce the failure observed at the road.The main purpose of the work was developing a durability benchtest to the body region where the exhaust vehicle system isattached. This test should be correlated in damage and failure withthe road, to be used as a reliable alternative to evaluatedurability behavior of this body region. At end, results from roadand bench test were compared
