摘要
以VMC850B立式加工中心床身为研究对象,以最大变形量为目标,对4种典型工况进行分析与比较,以刀具位于工件右侧的工况作为首要考虑条件,对床身进行了静动态特性分析。选用8种常见材料,运用层次分析法对床身铸造材料进行优化分析。优化前后床身的静动态性能结果表明:在保持床身原有结构及设计前提下,玄武岩纤维树脂混凝土材料整体静动态性能最优,可直接运用于现有结构中,满足机床静动态性能要求,可为其他研究提供理论基础。
The VMC850B vertical machining center bed is taken as research object,and the maximum deformation is taken as the goal.Four typical working conditions are analyzed and compared.When the tool is located on the right side of the workpiece,which is taken as the primary consideration,the static performance of the bed is analyzed.8 kinds of common materials are selected and the optimization analysis of the casting materials of the machine bed is carried out by using the analytic hierarchy process.The results show that in the original structure and design of the bed,the static and dynamic performance of the basalt fiber reinforced polymer concrete material is the best.It can be directly used in the existing structure,it meets the static and dynamic performance requirements of the machine tool.The theoretical basis is provided for other research.
