CFRP钻削工艺能耗属性及其与制孔质量自适应优化研究

航空、航天等高端制造领域碳纤维增强复合材料(CFRP)使用比例大幅增长，CFRP构件大规模生产已经展开,虽可降低CFRP成本，但所面临的降耗减排与质量提升等问题也会日渐突出。面对日益增长的CFRP需求，本课题以耗能较多、质量控制更复杂的钻削工艺为研究对象，创新性地将能耗指标引入到CFRP质量评价中，通过对CFRP钻削过程中不同阶段质量缺陷产生的原因及其产生过程中功率与能耗变化规律的分析，揭示CFRP钻削过程能耗变化特性及其与钻削质量完整性间的映射关系，挖掘基于能耗变化的质量缺陷诊断规则，并进行多模型融合决策；突破CFRP钻削过程实时在线质量监测与提升方法的难点和瓶颈，提出一种融合工艺能耗特性的复合材料钻削过程能耗与表面质量自适应优化方法，进一步完善CFRP钻削质量评价体系。研究成果对提高CFRP加工质量、缓解我国碳排放压力，尽早实现碳达峰和碳中和都有积极促进作用，应用前景较广阔。

With a significant growth in proportion of composite materials and titanium alloys in aviation, aerospace and other high-end manufacturing fields, the CFRP components mass production has begun. Although mass production can reduce the cost of CFRP, the issues of quality improvement, energy saving and emission reduction will become increasingly prominent. Facing the increasing demand of CFRP, this research takes the drilling process which consumes more energy and has more complex quality control as the research object, and creatively applies the energy consumption index into the CFRP quality evaluation. Based on the analysis of the causes of quality defects in different stages of CFRP drilling process as well as the change of power or energy consumption in the CFRP drilling process. The mapping relationship between energy consumption and drilling quality integrity in CFRP drilling process is revealed. Then the association rules between energy consumption and drilling quality are mined and multi model fusion decision is made. Moreover, to break through the difficulties and bottlenecks of real-time on-line quality monitoring in CFRP drilling process, an self-adaptive optimization method for energy consumption and surface quality integrating process energy consumption characteristics is established to further improve the quality evaluation system of CFRP drilling. The research results will have a positive role in improving the CFRP processing quality, alleviating the pressure of carbon emission in China and realizing carbon peak and neutral earlier.
