A bearing is considered non-ideal if the errors in its manufacture cannot be neglected in the context of the problem being solved. Many important problems of contact stiffness and contact stress require that the bearing be considered precisely as imperfect. The STC APM has developed a universal method for solving contact problems, the reliability and efficiency of which have been confirmed by the results of experimental studies.
APM Bear performs a full range of verification calculations, when the output characteristics of the bearing are calculated from the known geometry of the bearing. When determining the output characteristics, original analytical and numerical approaches are used, as well as mathematical modeling methods, which makes it possible to present the results of calculating these parameters and the magnitude of their statistical dispersion in a user-friendly form (table, graph, histogram). In particular, it is possible to describe the behavior of bearings in real time using an animation procedure.
The whole complex of solutions obtained provides the user with the opportunity to visually, both qualitatively and quantitatively, evaluate the suitability of a bearing (or a pair of bearings) and, if necessary, outline ways for selecting parameters for more efficient bearings.
