摘要:To decouple the equation of non-classical viscous damping random dynamic systems, Paired Complex Modal Displacement (PCMD), which denotes paired displacement for the complex modal and its conjunction, is introduced in this paper. The modal decoupling approach for the equation of non-classical viscous damping random dynamic systems, based on the PCDM is applied to linear discrete systems. The implementation leads to a simpler method of random response analysis under random excitations. Furthermore, the pseudo excitation method for power spectral density matrix analysis is applied in this paper. Compared to traditional methods of the correlation matrix and power spectral density matrix analysis, it is demonstrated that the efficiency of random vibration analysis could be further improved.
