摘　　要：某自动炮的间歇机构选用了圆柱分度凸轮机构,为了适应武器平台的总体轻量化要求,圆柱分度凸轮是自动炮进行轻量化的目标之一。为了能够准确地对圆柱分度凸轮进行轻量化,依据结构参数建立了圆柱分度凸轮的数学模型,并运用UG NX软件的运动仿真模块实现了圆柱分度凸轮的精确物理建模;再以轻质材料应用为轻量化途径切入点对圆柱分度凸轮进行了有限元分析;最后结合分析结果进一步开展了轻量化结构设计并进行了实物验证,轻量化效果明显。研究过程能指导自动炮用圆柱分度凸轮的轻量化设计。An automatic gun uses cylindrical cam mechanism,this cylindrical cam mechanism needs to be optimized to reduce weight to meet the lightweight requirements of weapon systems.In order to accurately lighten the cam,a mathematical model was built;the UG NX software motion simulation function was used to obtain an accurate cam model,the finite element analysis of the cam was performed using lightweight materials as the path,and then lightweight design and physical verification on the cam based on analysis results was performed,the effect of lightweight optimization is obvious.The research process can guide the lightweight design of the cylindrical cam mechanism of the automatic gun.
