Fatigue Tests - Important Part of Development of New Vehicles

In city of Pilsen (Czech Republic) modern transport engineering is developed. The Skoda Transportation (production company) has successfully been producing rail and road vehicles for many years (electric locomotives, trams, metro cars, trolleybuses, battery buses). This producer cooperates in developi...

Design, service and testing grounds stress spectra and their using to fatigue life assessment of bus bodyworks

In the development of a road vehicle such as a bus, the input data for the assessment of the fatigue life of the body and other mechanicalparts of the vehicle are gradually refined. In the initial phase of the development of a new vehicle, so-called design stress...

Using design S-N curves and design stress for probabilistic fatigue life assessment of vehicle components

The contribution explains a possibility of using design S-N curves and design stress spectra for probabilistic fatigue life assessment of vehicle components. The design S-N curves can be considered on the basis of either experiments or using some standards. The design stress spectra...

Parametric study of the potential of application of high-strength steels to increasing the service fatigue life of vehicle structures

The paper highlights the main impacts of HFMI technology on increasing the fatigue resistance and extending the fatigue life of joints and components welded from both conventional and high strength steels. Parametric calculations of the permissible stresses of a selected structural detail&#x...

Use of IRNDT evaluation for crack detection induced by cyclic loading

Infrared nondestructive testing is an inspection method based on an external excitation of a measured sample and a thermographic analysis of its thermal response. It often uses advanced evaluation techniques based on temperature spatial and temporal changes. IRNDT is a suitable method f...

Heat treatment of closed-die forgings of low-allow AHSS steels

New methods are sought today for improving the mechanical properties of heavy-duty parts of high-strength steels, particularly in the automotive industry. AHS steels tend to be associated with high strength and hardness, which are achieved at the cost of poor ductility. Nevertheless, du...
