Modeling of selected load-bearing structures using the truss and beam elements

Abstract

Abstract. The article presents the methodology of adjusting the usable properties of rodlike and beam elements for modeling the complex load-bearing structures. The basic object of consideration was the single-row slewing ball bearing. In this paper the mapping issues of usable qualities of the slewing bearings are summarized in relation to use of the finite element method. The emphasis is primarily on using the rod-like and beam elements for modeling the contact phenomena in the ball-raceway contact zone. In addition, ideas for use of the beam elements to modeling bearing bolts were presented.Keywords: finite elements type of truss and beam, contact zone ball bearings-raceway, slewing bearings, computational mechanics

The FEM Application in Numerical Analysis of Slewing Rings Roller/Ball Combination Bearing

“…Basically, they should be determined separately for each bearing, but a certain set of the typical characteristics of the rolling elements for the same sizes of the elements and similarity in shape of intersection of bearing rings can be prepared. Rollers were substituted by the non-linear springs connected to nods of a mesh of bearing rings, as was applied in the numerical modelling in [8,9].…”
