钢纤维聚合物混凝土机床床身动态性能仿真

研究了一种新型的复合材料-钢纤维聚合物混凝土，用它来做机床的基础件，其静动态性能优于传统的灰铸铁床身，从钢纤维聚合物混凝土的实验材料和制备方法入手，利用力学原理简单研究了钢纤维的增强机理，并且利用有限元的方法，对机床的床身进行模拟，得到了不同截面尺寸的固有频率，通过同结构的钢纤维聚合物混凝土和铸铁床身进行谐响应分析，证明了钢纤维聚合物混凝土床身良好的动态性能。

Dynamic function research of steel fiber polymer concrete machine bed

Studied a new composite material--steel fiber polymer concrete, which can be used in manufacturing the foundation of machine tool. The static and dynamic characteristics is better than the traditional cast- iron lathe bed. From the steel fiber polymer concrete's experiment material and the method of preparation the strengthen mechanism of steel fiber was studied with the mechanics principle in brief. This article uses the finite element method to simulate the lathe bed of machine tool, getting the natural frequencies of lathes with different section size and the respond curve of steel fiber polymer concrete and cast-iron lathe bed. Through simulation the good dynamic function of the steel fiber polymer concrete lathe bed was testified.
