Abstract

Conventional methods exist for obtaining the random vibration response of a finite-element model to “large-scale” turbulence, such as gust loading on an aircraft. However, this loading is random in time only. This paper presents a finite-element method for obtaining the response to “small-scale” turbulence that is random in space as well as time. Boundary-layer turbulence is an example of this type of loading. The method has been used successfully to find the random response of nonuniform, multispan tubes to inhomogeneous turbulent crossflow.
