| Abstract: | The moment equation method is generalized to deal with non-stationary random vibration of linear or non-linear systems subjected to wide-band excitations. Some general formulas are derived and used to several usual sorts of non-stationary random vibration. By calculating examples, it has been shown that the method is effective to solve wide-band excited nonstationary random vibration and has advantages over several other methods reported in some references in simplicity and convenience. |
