Launch Dynamics Analysis of a Grenade Machine Gun with High Muzzle Velocity Based on the Soft Recoil Technology

Abstract To study the dynamic performance of a grenade machine gun system with soft recoil technology and analyze floating mechanism parameters affecting firing dispersion, rigid-flexible coupling multi-body dynamics model was established. A twenty-round process simulated analyzed. The dispersion obtained based on external ballistics model, simulation validated by comparing numerical results experimental data. effects cradle force, projectile sparsity were discussed. show that GMG is well predicted are matched reasonably could improve reduce force.
