摘要：
To study the launch dynamic characteristics of Automatic Grenade Launcher(AGL), ammunition belt and three-legged were considered as flexible-body, and a rigid-flexible coupling model of the AGL was established by the software ADAMS and ANSYS. The load parameters such as breech pressure, gas chamber pressure of gas operated device, extraction resistance and spring acting force, were determined. The reliability of the model was validated. On this foundation, the dynamic characteristics of projectile, barrel, automatic mechanism, counter-recoil spring and feed mechanism, were researched. The effects of different firing angles and automatic mode on automatic mechanism motion characteristics were analyzed. The simulation results show that the design of this AGL is feasible. The short recoil-operated action and gas operation automatic mechanism make sure that the automatic mechanism can complete all function at different firing angles, and the feed mechanism works reliably.
