中文摘要: 针对固体润滑剂软涂层砂轮磨削时,润滑涂层在高温磨削环境下不能持续保持、易堵塞砂轮、未与磨削状况实时智能关联等问题,提出了基于转子动力学的纳米微粒在线内喷涂自适应涂层砂轮干式磨削加工的构想。其机理为:将润滑性能良好的纳米微粒通过内部喷涂工艺在线涂附在砂轮表面,并由实时监控磨削状况信号反馈控制涂层的形成,从而实现润滑涂层可持续保持,涂层性能良好且与磨削状况保持实时关联的目的。主要研究内容包括:揭示纳米微粒润滑涂层在内部驱动力作用下的黏结生成与保持机制,探索在线内喷自适应纳米微粒涂层磨削润滑机理,阐明纳米微粒在线内喷涂自适应涂层砂轮磨削润滑性能。本项目的研究意义在于:探索纳米微粒润滑涂层润滑磨削加工理论,为绿色制造工艺学科建设与发展提供理论指导,为实现绿色磨削加工具有重要的意义。

英文摘要: Due to the severe cutting friction, high gridning temperature and high pressure in cutting environment, solid lubrication coating of grinding wheels can not continue to maintain, easy to plug from the wheel and not real-time associated with grinding status. So, the thesis of adaptive coated grinding wheel by real-time sprayed inside with solid layered nanoparticle would be bring forward. The working principle is as follows: the grinding wheels would be coated with layered nanoparticles of good lubricating properties by inside spray real-time, and the lubricant layer parameters on grinding wheel surface would be controled by the feedback signal of grinding statue online, finally the lubricant layer on grinding wheel surface can be holded for long with good performance and matched real-time with grinding statue. The main research contents include: the generate and maintain mechanism of the nanoparticles lubricant coating by inside interaction would been exposed, and explored online nanoparticle inside spray adaptive coating technology would be study, the operated mechanism of the layerd solid adaptive nanoparticles coated by inside spray would be illustrated. The significance of this project is focused on: perfect green grinding theory, carry out green grinding, supplement theoretical of
