碩士 === 國立中正大學 === 機械工程學系 === 85 === In recent year ,machine tools have a lot of production in the market all over the world. Every country also make a lot of effort in research of machine tools. High speed and high precision are newly directions of the future development of machine tool technology. As a main part of machine tool, a build-in high-speed spindle is a key technology for such kind of development. The high heat produce by the build-in motor will make great damage to the bearing systems. The aim of this research is to develop a system of the analysis tools that can help engineer to design a better cooling system of the high speed spindle. First, we utilize CAD/CAM software I-DEAS and AutoCAD to build the shape model of the high speed spindle cooling system, and we use HyperMesh and I-DEAS to build the three-dimensional finite element model for cooling system. Next, we use several examples to investigate the accuracy of the structure heat transfer analysis software, TOPAZE-3D. Finally, we coupled fluid-structure program together and compare the analysis solutions with the experimental data. By use the solid- fluid coupled program, we can analysis the structure and fluid temperature distribution of I-BAG straight line cooling system and NCCU helical cooling system. By comparison the cooling effect of both cooling waterway in the design. At last, we use the methods of back-propagation neural network training method to find the real motor heat source in NCCU high speed spindle. All the analytical methods developed in this research can offer the spindle designer a new direction to improve design.
