More Than Shells, Grenade Rifle System Dynamics Simulation And Optimization Of Design,

The design thoughts of the rifle, shotgun and grenade launcher " Syncretizing in one" (Multi-Bullet Grenade Rifle) are brought out, In the view of the domestic and overseas background and the trend of the point and area target weapon .And the project of the sample-machine is introduced simply in this paper.The interior ballistic trajectory theory and aerodynamics theory are applied to the mathematics model which belongs to the principle of sample-rifle pushed by the gunpowder gas. With the rigid-body systematical kinetics theory, the 2-D and 3-D kinetics models and the kinetics parameters of the weapon are built up. The program for analysis and calculation has been written in VB language, and which can be used universally and definitely. Simultaneously the simulation and the optimization have been done with the software. Then the major laws have been found out which affects the function of the gas mixing, pipe-retreating weapon. Finally the weapon's 3-D model is set up with SolidWorks. Meaningful theoretical reference for improvement of the multi-bullet grenade rifle are provided, data and curve which are significant for future in-depth study are also obtained in this paper.
