Mechanical vibration systems are sometimes excited by stochastic forces. Such excitations may appear in all kinds of vibration systems, e. g. an automobile driving on a standard road, a centrifuge with erratic charge or a tall building waving in all weathers. Stochastic forces can not be represented by a single time function, a description by a stochastic process is necessary. Further, the response of the vibration system will be also a stochastic process. Therefore, the stochastic processes will be discussed in short at the beginning.
