General FEA

Many dynamics analyses involve general FEA models.  We have constructed detailed 3D models to obtain natural frequencies, forced response, and stresses.  Examples include:

Component vibration and stress, such as for blades and disks, for design and life prediction

General structures

pump assemblies

piping systems

shafts and housings

complete packages and skids

Isolation system design

specification/design of effective supports

6 degree-of-freedom natural frequencies

predictions of isolation effectiveness

analysis of individual isolation components for dynamic properties

To perform these calculations, we use Nx/NASTRAN, one of the leading general purpose analysis packages.  For a copy of a technical paper illustrating the use of this code with isolation system design and validation, considering seismic restraints, go to About Us.
