【摘要】：整体叶盘的表面质量和型面精度对航空发动机的气流动力性和使用性能影响巨大,而抛光是保证整体叶盘最终表面质量及型面精度的关键技术。针对目前国外对整体叶盘抛光技术及装备的严格保密、国内整体叶盘的抛光仍然广泛采用人工打磨的现状,对整体叶盘的抛光技术研究现状及发展趋势进行归纳总结,为整体叶盘的抛光及其自动化的发展提供参考。首先,概述了整体叶盘抛光加工的必要性及其重要性,分别从整体叶盘结构特性、材料特性和曲面特性等方面分析了整体叶盘的抛光工艺,并介绍了整体叶盘抛光工艺要求。然后,就整体叶盘磨料流加工、电解加工、砂带抛光等方面概述了国内外整体叶盘抛光技术及装备的研究现状,在此基础上提出了制约整体叶盘型面抛光技术发展的关键问题及其研究内容和解决方案。最后,根据整体叶盘的技术现状及核心关键问题指出了整体叶盘抛光技术的发展趋势。
[Abstract]:The surface quality and profile accuracy of the whole impeller have a great influence on the airflow power and performance of the aero-engine, and polishing is the key technology to ensure the final surface quality and profile accuracy of the whole impeller. In view of the strict confidentiality of the polishing technology and equipment of the whole blade in foreign countries, the present situation of manual grinding is still widely used in the polishing of the whole blade in China, and the research status and development trend of the polishing technology of the whole blade are summarized. It provides a reference for the polishing of the whole blade and the development of its automation. Firstly, the necessity and importance of polishing the whole blade disk are summarized, the polishing technology of the whole blade disk is analyzed from the aspects of the structure characteristics, material characteristics and surface characteristics of the whole blade disk, and the polishing process requirements of the whole blade disk are introduced. Then, the research status of integral disc polishing technology and equipment at home and abroad is summarized in terms of abrasive flow machining, electrolytic machining, abrasive belt polishing and so on. On this basis, the key problems, research contents and solutions that restrict the development of integral blade surface polishing technology are put forward. Finally, according to the present situation of the whole blade disc technology and the core key problems, the development trend of the whole blade disc polishing technology is pointed out.
