Identification of physical parameters in contact joints models of machines supporting systems
This article proposes a method of improving the accuracy of analytical models of machine tools supporting systems, by merging model analyses with experimental research of real construction. In this method, physical parameters of the model are identified on the basis of results obtained from experimental investigations of machine tools. The analytical model of construction is created in accordance with the concept of the rigid finite elements method, enriched with the possibility of contact joints modelling, according to the original idea of external loads correction. This article presents a software package, ESTES, which supports computations in the identification process. The required physical and geometrical data as well as the set of computations results are specified. This article also contains examples of parameter identification and concludes with the discussion of the results obtained and the conclusions deducted from analyses.
