摘　　要：弹库的出弹平台用于弹箱在水平方向上的转运与定位,以实现弹箱中弹药的步进式出箱供弹,而要想实现弹药的顺利供弹,弹箱在出弹平台上的定位精度就显得十分重要。针对出弹平台进给伺服系统,依据机械动力学原理,研究了摩擦、间隙和刚度等非线性因素对定位精度的影响,建立了包含有摩擦、间隙和刚度的综合数学模型。利用MATLAB/Simulink对系统进行了动态仿真分析。所得研究结论对实现出弹平台的准确定位提供了理论支撑。The jacking shells device of a magazine is used for cartridge box＇s transport and positioning,so as to realize the shell＇s single launch,and the positioning accuracy is very important to ensure the launching smoothly. Focusing on the feeding servo system of the jacking shells device of a naval gun,this article researches the influence of friction,clearance and stiffness on the positioning accuracy,establishes a comprehensive model which contains friction,clearance and stiffness on the basis of the mechanical dynamics principle,and analyzes the system＇s dynamic characteristics by MATLAB / Simulink. The conclusion provides theoretical support for the positioning accuracy of jacking shells device.
