摘　　要：传统的以铸铁或钢材为主的机床构件的性能优化已接近极值,而高速高精的加工对机床性能的要求进一步提高,树脂混凝土材料在机床基础件中的应用得到了广泛的关注。以CK5116数控机床为例,根据等价截面原则,设计了树脂混凝土材料的立柱模型,应用有限元方法对其进行静态分析、模态分析和谐响应分析,并与传统的铸铁材料机床立柱的分析结果进行对比。结果表明:同铸铁材料机床立柱相比,树脂混凝土材料机床立柱满足了轻量化的设计要求,且静刚度有所提升,其最大响应振幅在X轴、Y轴、Z轴的振幅缩减率依次为:55.18%、77.27%、20.88%。从而证明树脂混凝土机床立柱具有更优越的抗振性能。The performance optimization of the traditional machine tool structure for cast iron or steel is close to the extreme value,but the high speed and high precision machining requires the machine tool performance to be further improved.In recent years,the application of resin concrete in the foundation parts of machine tools has been widely concerned.The CK5116 Computer Numerical Control(CNC)machine tool is take as an example according to the equivalent cross section,its resin concrete column model is designed,combining with the finite element software on the static analysis,modal analysis and harmonic response analysis,and comparing with the traditional cast iron material of machine tool column.Comparing the results of the analysis,it demonstrated that the machine tool column is lightweight and the static rigidity is improved,and has better dynamic and static characteristic.The maximum response amplitude is decreased by 55.18%,77.27%and 20.88%respectively comparing with the maximum response amplitude of cast iron in X-axis,Y-axis and Z-axis.The results show that the resin concrete machine tool column has better anti-vibration performance.
