Generation of virtual track profiles using experiments and computer simulations

Marek Hejman, Vladimír Lukeš
An advantage of computer simulations of structures is the prediction of dynamic properties, loading, strength, fatigue life stability, etc. A new goal of computer simulations is the fatigue life analysis of vehicle structures or that parts. A "virtual track profile" (mathematical description of the track profile) can solve the problem of proper excitation. The paper describes one possible approach of virtual track profile generation. Experimental data and computer simulations are used for the profile generation.
