摘　　要：以硅酸盐水泥混凝土为内核主体、环氧树脂混凝土为外部包覆层的复合混凝土,将该混凝土应用到某型号卧式加工中心床身的制造,通过实验测试该复合材料的比热、导热系数、热膨胀系数等热性能参数,运用有限元分析软件Ansys workbench对床身进行稳态热分析和热-结构耦合分析,并且通过温度测试实验验证了分析结果的准确性,结果表明该复合混凝土机床床身与传统铸铁床身和树脂复合材料床身相比具有更好的热态性能.A new material of composite concrete consisting of silicate reinforced cement concrete inner coal and polymer concrete external coating layer is applied to a type of machine tool bed manufacturing. Experiment tests of thermal performance parameters of the composite material,such as specific heat,thermal conductivity and thermal expansion are conducted,and steady-state thermal analysis and coupled thermal-structure analysis are made by Ansys Workbench. The temperature test experiments verify the accuracy of the analytical results.The results show that the application of composite concrete machine tool bed has excellent thermal performance compared with the traditional cast iron bed and the resin composites bed.
