| Abstract: | The stationary random responses of complex 3D structures subjected to spatially coher-ent excitations are investigated and the pseudo-excitation algorithm is derived.This algo-rithm involves the cross-correlation items both between the participant modes and betweenthe excitations,and so it is a sort of complete CQC method.The auto-or cross-psd of var-ous structures can be computed efficiently and accurately. |
