The study of random vibration deals with random excitation processes and the response of vibratory systems to such excitations. The most frequent application is to vehicles (e.g., ships, trucks, airplanes, space vehicles) where the operational environment provides random dynamic excitation (e.g., stormy seas, rough roads, atmospheric turbulence, rocket engine noise). For an introduction to the field see [1, 2]. A survey of the present state of the art is provided by [3].
The various techniques available for the analysis of nonlinear systems subjected to random excitations are briefly introduced and an overview of the progress which has been made in this area of research is presented. The discussion is mainly focused on the basis, scope and limitations of the solution techniques and not on specific applications.
The application of dynamic mesh method has been extensively applied for simulating piston wind-induced subway environments, e.g. air quality, which is not central processing unit-friendly in calcul...
