Ocena stanu naprężenia w elementach bębna pędnego górniczej maszyny wyciągowej

Dimensioning rules of a mining hoist drive wheel that are actually in use, do not give a possibility to determine properly the stress and strain condition in the most afforded area of the structure, and the estimation of its fatigue life on that base is not possible. It seems necessary to undertake the effort aimed at development of the method to estimate the driving wheel elements technological condition regarding the fatigue phenomena. The results of dynamic analysis, strength analysis, and measurements verifying calculations that were made in actual object can make up a basis for further work on the revisal of relevant regulations. This elaborations may be considered as a step toward this enterprise continuation.
