Abstract

Many engineered structures are exposed to some type of randomly fluctuating dynamic loading. Random vibration analysis (RVA) provides a rational and efficient framework for the analysis of structures excited by such stochastic loads. Although research related to RVA has been underway in the U.S. for more than 30 years, it has taken a long time for this research to be implemented in practice. In recent times, RVA is being used more widely in practice for a variety of engineering problems, largely due to the availability of such analysis capability within popular finite element (FE) software such as ANSYS, I-DEAS, NASTRAN, STARDYNE, etc. This paper outlines the theoretical background of RVA, provides three examples taken from engineering applications, and presents some of the new features avail able in ANSYS since Version 5.0 for such analysis.
