Influence of the elastic and elastic-plastic material parameters on the mechanical properties of slewing bearings

Slewing bearings are critical components of rotating equipment. Large structure sizes and heavy working load conditions require an extremely high load-bearing capacity reliability. Overall local contact finite element models slewing verified by the empirical formula Hertz theory. Validated used to analyse influence elastic material (E 1) elastoplastic parameters (EP 1, EP 2 3) on carrying capacity. The following conclusions obtained comparing maximum load, stress, distribution full-circle deformation. bearing is investigated improve analysis accuracy bearings.
