摘要
为探索提高机床静、动态特性,从而满足机械制造向着高精密化、高自动化、高效率等方向发展需求的新途径,研究了一种新的机床基础件材料——玄武岩纤维树脂混凝土(BFPC)。确定了BFPC主要性能参数,并以某数控机床铸铁床身为研究原型,设计了BFPC机床床身。应用有限元分析软件ANSYS分析原型床身和BFPC床身的静动态特性,得出了其应力-应变分布云图、前6阶模态振型图、固有频率及谐响应曲线,并将上述结果进行对比分析。结果表明,以BFPC制造机床床身可在减轻质量的同时提高床身的静、动态特性。
In order to explore a new way of improving the static and dynamic characteristics of the machine tool to meet the requirement of the mechanical manufacturing towards high precision, high automation and high efficiency development direc- tion, a new kind of machine tool base materials-basalt fiber polymer eoncrete（BFPC） was studied in this paper. The BFPC main performance parameter was determined. A CNC machine cast iron bed was taken as the research object to design the machine tool lathe bed of BFPC. The static and dynamic characteristics of the two kinds of bed were analyzed using the finite element software ANSYS so as to get the strain and stress distribution diagram, first 6-oreder mode vibration diagrams, natural frequency and harmonie response curve. The results above were compared. The results showed that the manufactured machine tool lathe bed using BFPC could reduce the weight and improve the static and dynamic characteristics of the lathe bed at the same time.
