WebThe most widely used and studied dynamic substructuring methods are classical linear techniques such as the Craig-Bampton and MacNeal-Rubin methods. These methods are widely studied and implemented in many commercial FE packages. How-ever, as linear methods they naturally break down in the presence of nonlinearities. http://www.vibrationdata.com/tutorials2/component_mode_synthesis.pdf
WebAug 1, 2012 · For the purpose of investigating both the influence of the master DoF and the number of the accompanying Craig–Bampton (CB) modes, five case studies were conducted . The number as well as the position of the master DoF is depicted in Fig. 5. For each case study, the MOR schemes are applied for four different CB sets, i.e. … WebCraig-Bampton model for linear systems, and is readily applied to systems built directly in a commercial FEA package. The nonlinear, reduced modal equations for each subcomponent are then coupled by satisfying compatibility and force equilibrium. The efficiency of this new substructuring approach is demonstrated on an

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.
