摘　　要：由于固体火箭发动机翼柱形药柱结构的特殊性以及在加工过程中由于机械冲击、摩擦及静电等因素,存在易燃爆的危险性,针对此特点设计出了药柱整形虚拟轴机床的结构和对药柱整形加工的方案,并借助一种基于LabVIEW的虚拟频谱分析软件对该虚拟轴机床进行实验模态的理论研究,从而为评价该机床的性能以及使其机械结构不断优化奠定了基础。Aimed at the special structure of the wing cylindrical grain of solid rocket motors and the risk of exploding because of mechanical impulse, friction and static charge in the processing, a virtual-axis machine tool was designed to process the wing cylindrical grain, and the processing project of shaping grain was presented. The theoretical research on the experimental modal of virtual-axis machine tool was carried out based on the spectral analysis software of LabVIEW. The research provides the basis for evaluating the performance and optimizing the structure of the virtual-axis machine tool.
