.30 Mm Automatic Shells Chain For Shells Features Match

In this paper, according to the matching problem on the feeding characteristic of 30mm automatic gun, the equations of a robot with Kinematics constraints are derived, which the theory of Descartes Kinematics and Dynamic of Rigid Multi-body. The movement characteristic of every Rigid-body on the link belt (cartridge link with bullet) has been described, the analysis on the load characteristic on the link belt when feed. On the simulation, based on the3-dimensional model software system SolidWorks and the dynamical analysis, software system ADAMS, the impact and contact have been simulated by equivalent spring and pamper model, the3-dimensional model of feed mechanism and link belt which relative to the inertial frame and the dynamic analysis model of the gemel containing clearance have been found, the simulating calculate on the model has been done, the contrastively analysis on the result and tests has been done. Based on a great deal of test on the process of the item, the quantitative analysis on the fault mechanism of tow feed characteristic match that the offset on grenade and the cracking up of Armor-Piercing Discarding Sabot(APDS)'s sabot, the validity of the improve measure used on the research process of the item has been proved. In this paper, the introduction and design characteristic analysis on the 30mm automatic gun system and its feed mechanism and link belt have also been done, especially the settlement process, project and measure on the matching problem of the tow feed characteristic have been generalized, which can be used by the improve design of the automatic gun system as a reference.
