Strength analysis of welded joints in support structures of heavy machinery subjected to changeable loading conditions

Tadeusz Smolnicki,
Piotr Sokolski

Abstract: The durability of bearing units of large machines depends mainly on the condition of their welded joints. With this in mind, we developed numerical models of the analyzed bearing units, for which we performed FEM simulations of the stresses in welded joints in several basic load cases. In each of the respective variants the technical condition of the bearing nodes was different and it corresponded to the severity of the degradation processes. Different positions of the superstructure in relation to the underca… Show more
