项目摘要
In recent times, research has been increasingly conducted on alternate materials for machine frame components, traditionally made from steel or polymer concrete. Environmental as well as economic aspects are becoming more important in construction design and -development. Hence, this research project is focused on an overall investigation of ultra-high performance concrete (UHPC) as machine frame material. UHPC is a further development of traditionally concrete. UHPC, compared to conventional concrete, has significant higher strength parameters, a more dense structure and a substantial improved durability. Isolated fields of application in machines for wood and composites machining already benefit from UHPC in machine frames. It is intended to expand the field of application to machine tools for metal machining, even if coolants are used.To the time, there are only a few construction guidelines and the most of them come from polymer concrete. Hence, an aim is to make basic research on calculating UHPC machine frames. The calculations will be verified on different UHPC to afford a realistic structural design of machine frame components. An additional aim is the optimization of concrete design with respect to application in mechanical engineering and also the differences in bending tensile strength under different moisture conditions. Further values to investigate are the deformation values, surface accuracy, the chemical durability after contact with process fluids and also the shrinkage behavior.The first part of the project restrict only the aspect of the influence of operating fluids to UHPC. The focus lies in the interaction between UHPC with water and other for machine tools typical operating fluids like cooling lubricants and the equivalent changing of the mechanical characteristics.
近年来,人们越来越多地研究传统上由钢或聚合物混凝土制成的机器框架部件的替代材料。在建筑设计和开发中,环境和经济方面正变得越来越重要.因此,本研究计划的重点是超高性能混凝土(UHPC)作为机器框架材料的全面调查。UHPC是传统混凝土的进一步发展。与传统混凝土相比,UHPC具有显著更高的强度参数、更致密的结构和显著改善的耐久性。在木材和复合材料加工机械中的孤立应用领域已经受益于机器框架中的UHPC。即使使用冷却剂,也可以将其应用范围扩大到金属加工用机床。目前为止,只有少数几个施工指南,其中大部分来自聚合物混凝土。因此,对超高性能混凝土机架的计算进行了基础性研究。计算将在不同的UHPC上进行验证,以提供机器框架组件的实际结构设计。另一个目的是优化混凝土设计在机械工程中的应用,以及在不同湿度条件下弯曲拉伸强度的差异。需要进一步研究的值包括变形值、表面精度、与工艺流体接触后的化学耐久性以及收缩行为。项目的第一部分仅限于工作流体对UHPC的影响方面。重点在于UHPC与水和其他机床典型工作流体(如冷却润滑剂)之间的相互作用以及机械特性的等效变化。
