Design And Simulation Of A Self-propelled Artillery Semi-automatic Feed Transfer Mechanism

Taking the design and study of one self-propelled artillery semi-automatic machine asthe research background, based on the analysis of different ways of ramming, the overalldesign of the semi-automatic ramming mechanism was proposed, a new arm-type feedtransfer mechanism was adopted as the ramming device. By analyzing the structure andworking theory of the arm-type feed transfer mechanism, various parts of the rammingmachine were designed in detail, and three-dimensional model of ramming machine wasestablished with the help of 3D CAD modeling software SolidWorks. The motioncharacteristics of this arm-type ramming machine were obtained through kinematic analysis,and the characteristics of this ammunition deliver process were obtained through simulationsoftware ADAMS. In order to guarantee the stability of the projectile movement and reducethe damage of the cartridge belt caused by the ammunition delivery process, the arm-typeramming machine improvement project was put forward based on the simulation andanalysis of the simplified ramming mechanism. The positive function of this improvedramming machine is protecting the belt and reducing the swing of the projectile, whichverified by the contrast of the simulation and analysis of the ramming machine before andafter improved. The drive motor parameters of arm-type ramming were estimated in thisthesis, and some requirements on the choice of the motor were pointed out. At the end ofthe article, preliminary test scheme on semi-automatic ramming machine was alsodiscussed.Arm-type semi-automatic ramming machine is still in the research and developmentstage, the research methodology used in this thesis and the conclusion concluded in this research could provide a basis and reference to arm-type semi-automatic rammingmechanism design and further research.
