摘要
以150m/s超高速平面磨床为研究对象,利用PRO/E建立其各部件的三维几何模型,利用HYPERMESH进行有限元前处理建立各部件的三维有限元模型,在此基础上对机床结合部进行定义得到磨床整机动力学模型.并利用有限元计算软件ANSYS进行整机模态分析,初步识别了该类型磨床结构的薄弱环节,为超高速平面磨床结构的改进设计提供依据.
The dynamic characteristics of a super-high speed surface grinder （150 m/s） were studied. PRO/E was used to set up the 3D geometrical model of each component and Hypermesh was used to set up the 3D FEM model, 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.
