In this study, the recoil movement of heavy weapons with hydropneumatic recoil mechanism is modeled. The primary purpose of the study is to obtain the equation of motion of the recoiling parts in the weapon systems. For this purpose, the forces acting on the recoiling parts were determined, and the effects of each force were examined. Breech force is calculated via LeDuc equations for in bore period and verified by comparing with experimental studies. The breech force which is generated during the discharge of the remaining gases after the projectile leaves the barrel is also calculated and the total recoil force is obtained. Recoil motion caused by breech force is retarded by hydraulic brake and recuperator force in the recoil mechanism and friction. After determining breech and net retarding forces, the equation of motion is solved in MATLAB and the recoil distance is obtained. Calculated recoil distance, breech force and projectile velocity values are compared with test data and model is validated.
