中文摘要
由纤维增强塑料(FRP)制成的轴,由于其密度低、刚度高,在某些行业中已成功地取代了钢轴,例如在造纸和印刷机中。玻璃钢轴的机械和热性能主要由纤维角度决定,因此设计者可以控制这些性能。目前,玻璃钢轴的传力元件是由金属制成的,并使用结构胶粘剂或压配合来安装。这些解决方案是不可拆卸的,通常占总重量的很大比例,因此限制了玻璃钢轴在特定应用中的使用。该项目的目标是研究轻量化的优化、可拆卸的力传递元件,以便使玻璃钢轴的优势能够在更广泛的行业中使用。电主轴是需要带可拆卸传力装置的轴的一个示例应用。特别是机械加工的螺纹及其优化将是本次研究的主题。将进行静态和疲劳强度测试,以调查旋转FRP轴上的缺口影响。
英文摘要
Shafts made of fiber reinforced plastics (frp) have, due to their low density and high stiffness, suc-cessfully replaced steel shafts in certain industries, for example in paper and printing machines. The mechanical and thermal properties of frp shafts are predominantly determined by the fiber angle, thus giving the designer control over those properties. Currently force transmission elements for frp shafts are made of metal and are fitted utilizing struc-tural adhesives or press fits. These solutions are undetachable and often contribute a significant proportion of the overall weight, thus limiting the use of frp shafts to specific applications. Goal of this project is to investigate lightweight optimized, detachable force transmission elements, in order to make the advantages of frp shafts accessible for a wider range of industries. Motor spindles represent an example application where shafts with detachable force transmissions are needed. Especially machined threads and their optimization will be subject of this investigation. There will be static as well as fatigue strength testing to investigate the notch effect on rotating frp shafts.
