摘要
以小口径超精密数控磨床为研究对象,利用CATIA建立其各部件的三维几何模型.通过有限元软件ANSYS分别建立工件轴部件、磨轮轴部件及机床整体的三维有限元模型,并对工件轴部件、磨轮轴部件以及磨床总体进行了模态分析,根据分析结果识别该类型磨床结构的薄弱环节,为小口径超精密磨床结构的改进设计提供依据.
The dynamic characteristics of a small caliber ultra-precision NC grinder were studied. CATIA was used to set up the 3 Dgeometrical model of each component,upon which the whole machine model was established. Then,mode analysis was carried out with ANSYS and the weak points of the structure were identified. This will provide reliable evidence for the optimization design of structures.
