Application of Hybrid Modeling Techniques for Computer Related Equipment - IMAC 15

P.Avitabile, F.Piergentili, K.Lown

Analytical models of desktop computer assemblies are typically generated using finite element modeling techniques to develop adequate physical design parameters such as chassis stiffness, hard disk drive mounting, etc. Accurate finite element representations of components in a chassis assembly, such as the power supply, are not easily developed and attention must be paid to appropriate modeling of component attachment points. Consequently, finite element models of the assembled system can become quite large due partially to the need to adequately describe the dynamics of the system at higher frequencies.

Hybrid modeling is a common technique used for the development of substructured system models. This technique can overcome some of the difficulties that trouble the development of a large assembled system model. Hybrid modeling is useful for both experimental and analytical models. This paper presents the results of the application of these hybrid modeling techniques for some computer related equipment applications. The advantages and shortcomings of the technique are discussed relative to the use of the technique with models and data on actual hardware configurations.
