SimAcademy Webinar Archive: Vibration Fatigue Analysis Using MSC Nastran (PART1)

MSC Nastran embedded vibration fatigue life estimation, when used early in a development design cycle has the potential to greatly enhance product life as well as reduce testing and prototype costs, thus ensuring greater speed to market. This computationally efficient procedure provides life estimates orders of magnitude faster, with only a small fraction of system resources compared to traditional methods that are using Time domain. Frequency domain methods for structural analysis also offer superior qualitative information about structural response.

SimAcademy Webinar Series: How to Validate a CMS External Superelement

MSC Nastran allows for the creation of a reduced, matrix-based representation of a Finite Element Model. This reduced representation is referred to as a Superelement. When creating a Component Modal Synthesis version of the Superelement, there are 3 main considerations: What DOF go on the boundary, Should those boundary DOF be fixed or free, and How many component modes to retain This presentation will focus on how to validate that the reduced model represented by the Superelement appropriately represents the unreduced component. A particular form of Superelements, External Superelements, will be used.
