A System Identification Methodology Using Dynamic Data for Analysis of Mechanisms.

Abstract

Signals representing the force and displacement of the table of the M-139 machine gun during firing were analyzed. A constrained ARMA (2,1) model was fitted to the displacement data to explain the reason why the gun was jammed. Force data during and after firing were represented by the 4th and 6th order stochastic differential equation models. These models after decomposing yielded the dynamics of three subsystems; a supporting table, a recoil system and a bolt assembly. (Author)
