Webfirst is a Craig-Bampton mass and stiffness matrix representation of a spacecraft to be tested on the shaker table. The second is a lumped mass representation of the spacecraft including rotational inertia properties located at the spacecraft center of gravity (CG). These models provide two extreme dynamic response cases for the shaker table.
