Dynamic Simulation and Analysis of a Certain Type of Submachine Gun Automaton Based on ADAMS
In order to study the motion law and dynamic characteristics of a certain type of submachine gun automaton,and fur-ther explore the influence of the size of air guide hole on the motion cycle of the automaton,firstly,the three-dimensional solid model of the submachine gun automaton is established using UG software,then the virtual prototype is built in ADAMS software,and the internal trajectory and air guide chamber pressure curve are fitted using Matlab software.The single shot of the gun is simulated to obtain the dynamic characteristics of the gun and the gun frame,such as the displacement-velocity and compound spring pressure curves.Compared with the test data,the simulation results show that the virtual prototype model has a high feasibility.Finally,the influence of the pilot hole size on the automaton motion cycle is analyzed.With the diameter increase of air guide hole,the recoil speed and recoil impact are expanded,the recoil speed is significantly increased,the recoil time is significantly reduced,and so does the au-tomatic cycle time,which provides a theoretical reference for the optimization design of product.
