摘要(Abstract):

应对大尺度曲面复合材料的成型切割工程,本文基于高精度、高速度的切割要求,在美国波音公司水切割应用基础上提出了以提高工作压力来确定高端的水射流工况,在反复的试验基础上建立数学模型,以超高压水切割加工中心成套装备的可靠性运行为目标进行水切割机构的闭环设计。通过应用实例,本项目得出超高压水射流可靠运行与其对复合材料的高精度、高速度切割作业的对立统一经验。本项目理论研究、结构设计、试验应用很好地适应机翼复合材料加工的高技术要求。由此可见,在可靠运行前提下提高工作压力对高精度、高速度加工复合材料是极为重要的。
For large scale curved composite components cutting process engineering application,considering high precision and high speed cutting requirements,this paper proposed to improve the working pressures as high-end water cutting working condition which is based on Boeing water cutting application. Mathematical model was established based on lots of complicated tests,and cutting mechanism with the aim of ultra high pressure water cutting processing center equipment reliability was designed. Through the test application examples,it is showed that high precision and high speed water cutting composite components is corresponding to reliable water cutting processing operation. The theoretical research,structural design,test application of the project in this paper was well adapted to the high technical requirements for composite craft wing processing. It can be seen that it is very important to improve the working pressure to reach high precision and high speed composite components processing under the premise of reliable operation.
