Analysis of a Balanced Breech System for the M1A1 Main Gun System Using Finite Element Techniques

Abstract

A DYNA3D finite element (FE) analysis was used to help determine the observed behavior of the M256 gun system during the balanced breech experiment. The experiment was conducted to see if balancing the breech block on the M256 would unprove the overall gun system's performance. The experiment, although partially successful, revealed some unsuspected results. The analysis in this report uses an advanced numerical model of the entire M256 system to deduce a possible explanation of the observed behavior. Results generated during this study also indicate possible modifications that can be made to the recoil which will enhance its performance.
