DYNAMIC RESPONSE OF A WEAPON SYSTEM WITH STOCHASTIC EXCITATIONS.

Abstract

A machine gun system under steady firing, subjecting to periodically stochastic breech forces and purely stochastic support points excitations is considered. The system dynamic equations are cast into a matrix equation in the context of a multiple input and output system using relevant theory of stochastic processes. A 'direct method' is utilized to find the complex frequency response functions. For given Gaussian stationary excitations, the response displacement spectral densities and the correlation functions are determined. Subsequently, the means and variances of the response are obtained. These values render the response probability density functions. A numerical example is considered and numerical results are given. As specific interests, the effects of some firing rates and supporting points excitations on the mechanical dispersions of the system are shown respectively.
