某浮动式自动机动力学建模仿真研究

摘要

在分析某小口径高炮浮动式自动机拓扑结构基础上，以 ADAMS为分析平台，研究闭锁力的力学模型和在ADAMS中的施加方法，建立自动机的虚拟样机模型并进行有效性验证；分析自动机的动力学特性，研究不同可调流孔面积对自动机浮动性能的影响，确定可调流液孔面积合理范围为20 mm2~40 mm2.%The topologic structure of floating automatic mechanism of a certain anti-aircraft gun is analyzed.Based on ADAMS software,the force model and applied method in ADAMS of dead-lock force are researched,and virtual prototype of floating automatic mechanism is built.The validity of virtual prototype is verified.The dynamic characteristics of the floating automatic mechanism are analyzed,and the effects of different areas of the adj ustable liquid flow holes on the floating automatic mechanism’s characteristics are researched.The suitable adjustable liquid flow holes area should be between:20 mm2~40 mm2 .
