In the paper, on the basis of existing approaches to the analysis of turbine blades Z-like shroud platforms contact surfaces interaction the methodology of beadless shroud platforms characteristics analytic definition was developed taking into account the influence of accuracy with which the rotor wheel elements are manufactured. There was accomplished the analysis of design factors influence on contact surfaces wear and, using 3D finite element models, the mechanism of temperature and operating time influence on the performance of the deflected mode of the blades wich different shrouding types is defined.
