为了进一步研究国家制造领域的前沿课题和研究热点,例如航空发动机叶片多为强扭曲、薄壁、自由复杂曲面,其检测、特别是生产现场的检测,全面分析了现行叶片常用测量方法的原理及技术特点,总结凝练了叶片测量的关键技术,指出高精度、高效率、全信息、一体化是叶片测量的基本要求和发展趋势.讨论了中国在测量基础理论研究、装备关键技术开发上与国外先进国家的差距,并指明了中国需要着重发展的技术与对策.分析表明:中国航空发动机叶片目前还缺乏有效的测量手段,通过原理创新,为解决叶片精度检测找到可行的办法,具有现实紧迫性.基于整体误差分析理论的新型叶片测量技术方案,实现了叶片全部质量信息的快速获取、质量评定和工艺误差分析,具有良好的发展前景.
In order to further study the frontier topics and research hotspots in the field of national manufacturing, for example, most of the blades of aeroengine are strongly twisted, thin-walled and free complex curved surfaces, and their detection, especially on the production site, comprehensively analyzes the principle of the commonly used measuring methods of blades and This paper summarizes the key technologies of blade measurement and summarizes the key technologies of blade measurement and points out the basic requirements and development trend of high precision, high efficiency and all information and integration.It also discusses the basic theory of measurement and the development of equipment key technologies in China The gap between the advanced countries and pointed out the technology and countermeasures China needs to focus on.The analysis shows that there is still a lack of effective measurement methods for China’s aeroengine blades at present and it is urgent to find a viable solution to the blade precision detection through principle innovation Based on the theory of global error analysis, a new scheme of blade measurement is proposed to realize the rapid acquisition, quality evaluation and process error analysis of all the blade quality information, which has good prospects for development.
