Safety of the wheels for high-speed train was investigated when the tread cleaner, which play a role in the increase of adhesion and the removal of dirt, is failed and stuck in wheel tread. The present study was performed on the basis of analyses of a combination of mechanical and thermal load due to the failure of tread cleaner during severe conditions. The finite element method was used to an...

Abstract The airless tires are developed to overcome a disadvantage of pneumatic tire which lost maneuverability caused flattening and blasting. finite element analysis (FEA) is an effective method for development have complex construction. material properties describe mechanical behavior each component very important yield accurate result. high order constitutive model usually obtains the accu...

Driving wheel operation is characterized by force interactions with the ground, manifested in form of vibrations. Signals generated driving wheels can be analyzed frequency spectrum tractor drawbar pull. The paper presents analysis a pull signal equipped two types special and standard tires. Beside evaluation wheels’ properties according to power, spectra measured signals were using fast Fourie...
