A symmetric Craig‐Bampton method of coupled fluid‐structure systems
Abstract
A symmetric Craig‐Bampton method of coupled fluid‐structure systems is developed. The reduced matrices of the substructure have the same features as those of conventional substructures. Thus, standard procedures can be applied to assemble and solve the equations of the complete system. To solve the eigenvalue problem related to the substructure a special subspace iteration procedure is presented. The method can be applied to fluid‐structure systems with compressible or incompressible fluids. Constant pressure modes can be dealt with by a convenient separation technique.
