The role of Computer Aided Engineering in research as well as product development has been significantly increased during two last decades. The growing demands on the simulation address not only monodisciplinary phenomena but also phenomena from
different engineering branches. The current state-of-the-art simulation tools allow two basic approaches for meeting the demands, either coupling of various specialised simulation codes or application of multiphysical simulation tools.
This paper focuses on the simulation approaches for the multidisciplinary tasks and particularly on the connection of specialised simulation tools by interfaces. It classifies the interfaces between specialised software packages in general and gives some case studies using the coupling of specialised simulation tools. Finally, the development stages of an interface between civil and mechanical systems are presented. and Obsahuje seznam literatury
Paper deals with subject of identification of aerostatic journal bearings dynamic properties with use of Rotor Kit Bently Nevada superstructure. Different bearing types were experimentally investigated and their static and dynamic characteristics were identified. Various methods of identification were used and spectral and modal properties of the system were calculated. Computer program was revised on the basis of experimental data. The influence of non-diagonal stiffness and damping elements was investigated by numeric stimulation. and Obsahuje seznam literatury
