Abstract [en]

Machine element analysis has the goal of describing functionality and other important aspects of machine elements in theoretical form. A rolling bearing is a typical example of a machine element. The first issue covered in this paper is how ideas from object-oriented programming and modelling can be applied to machine element analysis. The models thus obtained are easier to understand, better structured, and allow a higher degree of re-use than conventional models. Our conclusion is that an object-oriented model description is natural for the machine element analyst and is suitable for machine element analysis.

An equational model of rolling bearings is presented in this paper. The structure of the model is general, in three dimensions, and applies to many types of rolling bearings. Part of this generality is obtained by using parametric surfaces. In order to keep the presentation of the model understandable, we have simplified many details. Nevertheless, the model and one solution require approximately 200+200 equations. The model is also extensible, e.g., simple submodels of detailed properties can be made more complex without altering the overall structure.
