Analysis of the join between blade and stator disc in steam turbine

Popis výsledku v původním jazyce

The use of new method of attaching fixed blades to a stator disc led to the need for evaluating the strenght of a riveted joint. Conventional mechanical testing revealed large variations in the strenght of this joint. After sectioning involved numerical simulations using the DEFORM software, because securing additional samples for physical examination was complicated. The first simulation task focused on determining the tearing-out force, taking into account work hardening of the shank material due to plastic defromation. The second simulation task aimed to identify optimum initial dimensions of the shank. The goal was to ensure that the rotary upsetting process causes the shank to completely fill the hole in the shroud. As a result, the join strenght would be improved and, above all, the variation in strenght eliminated.
