Abstract
Abstract In order to improve the efficiency of rapid replenishment of chainless ammunition feeding system, the dynamics simulation analysis of the movement relationship between the driving sprocket and the shell and the handover relationship between the toggle wheel and the shell in the replenishment device is carried out for the replenishment device of chainless ammunition feeding system as an object. Firstly, based on multi-body dynamics theory and contact collision theory, the dynamics model of the reloading device is established by using multi-body dynamics analysis software RecurDyn, and the simulation and optimization are carried out on the tooth profile shape of the sprocket wheel and the movement path of the shell in the reloading device; Secondly, using the multi-objective optimization method, the key parts of the reloading device were strength-checked and parameter-optimized using the finite element analysis software Workbench. The simulation and optimization results show that the change rate of the movement speed of the shell is 5.01%, and the change rate of the handover speed between the toggle wheels is 6.46%, and the movement of the shell is relatively smooth, which can meet the engineering requirements; The correctness of the model and the feasibility of the optimization are verified, and the key parts of the recharge device achieve a weight reduction of 59.23% after the optimization, which provides a certain reference for the subsequent optimization of the recharge device structure.
