This paper presents the General Electric Aerospace Control Systems Department (ACSD) approach to hardware screening using random vibration as a stimulus. The proposed techniques were developed to achieve a screening program that is cost effective and is supportable in dollar payoff with increased productivity.

Abstract This chapter introduces the terminology of random processes and their properties; stationarity, correlation function, power spectral density, and the Wiener–Khinchin theorem. The theory of linear, causual, and time-invariant systems is presented, as is and their characterization in terms of impulse response and frequency ...

There is at present a great interest in random vibration as a special aspect of shock and vibration, especially in relation to effects on equipment. An attempt will be made to explain to members of the Acoustical Society of America (particularly those concerned with shock and vibration) what is meant by random vibration as opposed to other excitations ...

The calculated response of a uniform beam to stationary random excitation depends greatly on the dynamical model postulated, on the damping mechanism assumed, and on the nature of the random excitation process. To illustrate this, the mean square deflections, slopes, bending moments, and shear forces have been compared for four different dynamical ...

This note is concerned with the approximate solution of initial value problems for nonlinear second-order equations of type: \(u''+ \alpha g(u, u')+ \beta h(u)= f(t)\). In physical terms, these equations arise in nonlinear oscillations where \(g\) and \(h\) represent the damping and the restoring forces and \(f\) the external force. The author proposes

Abstract Random vibrations of vehicles are excited by stochastic guideway irregularities. The colored noise excitation processes are modeled by shape filters where especially the spatial character of real guideways has to be treated. The vehicles are modeled mathematically as multibody systems consisting of rigid bodies, springs and dampers.
