Dynamic Analysis of the 75MM ADMAG Gun System.

摘要

A detailed description of the finite element (lumped parameter) analytical simulation model of the 75mm ADMAG gun system, developed for the purpose of simulating the dynamic response of the physical system to single shot and burst mode firings, is herein presented. Model output consisting of natural frequencies, normal mode shapes and system response to a firing (including time-dependent trunnion and elevation link loads, and muzzle linear and angular displacements, velocities and accelerations) is presented. Model predictions for right and left horizontal, vertical and lateral trunnion loads and the elevation link load are correlated with experimental data obtained from a ten-round sample of 75mm APFSDS firings.
