摘　　要：本文以SKX-2030型龙门铣床工作台为研究对象,首先对工作台进行实体建模,然后利用有限元分析软件ANSYS对其进行有限元模态分析,得到其动力学特性,在分析其固有频率和振型的特点的基础上,并对其筋板结构进行分析和优化,使其结构更加合理。从而达到减轻自重、节约材料、降低噪声、延长使用寿命等目的,并为该类型机床的有限元分析提供依据。This paper taking worktable of SKX-2030 gantry type milling machine as the research object, the firstly, three-dimensional solid model of worktable is established, then, modal analysis to the model by using ANSYS and get its dynamic characteristics. The rib plate structure is analyzed and optimized based on analyzing the characteristics of its natural frequency and vibration mode for more reasonable. The proposed method can re- duce weight, save materials, decrease noise and extend service life, and it also provide theoretical basis for fi- nite element analysis method to similar machine.
