Abstract
A new approximate methodology for nonstationary random vibration analysis of multi-degree-of-freedom linear systems is developed. Simple analytical expressions for the covariance response are obtained which provide valuable insight into the nonstationary response characteristics and their dependence on the system and excitation characteristics. Reductions in computer time ranging from one to two orders of magnitude are achieved. The performance of the method is demonstrated by an example two-degree-of-freedom system.
