Stochastic or random vibrations occur in a variety of applications of mechanical engineering. Examples are: the dynamics of a vehicle on an irregular road surface; the variation in time of thermodynamic variables in municipal waste incinerators due to fluctuations in heating value of the waste; the vibrations of an airplane flying through turbulence; the fluctuating wind loads acting on civil structures; the response of off-shore structures to random wave loading.
Attention is focussed on problems of external noise. That is, models of mechanical engineering structures are considered where the source of random behavior comes from outside: e.g. a prescribed random force or a prescribed random displacement. The structures inhibit inertia, damping and restoring, linear and non-linear. Questions addressed are: how do these structures respond to random excitation, and how to quantify the random behavior of response variables in a manner that an engineer is able to make rational design decisions.
