| 摘要: |
| 磁弹磨粒具有磁性、低弹性模量以及优良的研磨性能，兼备粘结磨粒和松散磨粒的特点。双磁盘磁力钝化方法能极大地提高钝化质量和钝化效率。将磁弹磨粒引入到双磁盘磁力钝化法中，提出了4035硅胶磁弹磨粒的制备方法，根据磁弹磨粒的细观特性，采用有限元软件ABAQUS建立了磁弹磨粒的细观代表性体积单元（RVE）模型，分析了磁弹磨粒在拉伸和压缩状态下的应力应变规律。搭建磁弹磨粒双磁盘磁力钝化实验平台，对磁弹磨粒进行受力分析。通过磁弹磨粒双磁盘磁力钝化实验，研究了磁盘转速、磨粒粒度和相对磁导率对刃口磨损量的影响规律，并且验证了采用磁弹磨粒磁力钝化法，相对于磁性磨粒磁力钝化法和立式旋转钝化法，能够获得最大刃口磨损量和最大表面粗糙度降幅。研究成果对促进我国磁力高效加工和磁力光整加工技术进步具有重要意义。 |

| Abstract: |
| Magneto-elastic abrasive grains have magnetism, low elastic modulus and excellent abrasive performance, and have the characteristics of bonded abrasive grains and loose abrasive grains. The dual-disk magnetic preparation greatly improves the preparation quality and efficiency. Firstly, the magneto-elastic abrasive particles are introduced into the edge preparation of the dual-disk magnetic tool, and the preparation method of 4035 silica gel magneto-elastic abrasive particles is proposed. According to the microscopic characteristics of the magneto-elastic abrasive particles, the finite element software ABAQUS is used to establish the magneto-elastic abrasive particles. The meso-level representative volume element (RVE) model is built to analyze the stress and strain law of magneto-elastic abrasive particles under tension and compression. Secondly, an experimental platform for magnetic preparation of magneto-elastic abrasive particles with dual disks was built to analyze the force of magneto-elastic abrasive particles. Finally, Through the magnetic preparation experiment of the magneto-elastic abrasive dual-disk magnetic force, the influence of the disk rotation speed, abrasive particle size and relative magnetic permeability on the cutting edge wear is studied. And compared to the magnetic abrasive particles double-disk magnetic and drag finishing method, the magneto-elastic abrasive particle double-disk magnetic preparation method can obtain the maximum edge wear amount and the maximum surface roughness decreasing amplitude. The research results are of great significance to promote the progress of our country's magnetic high-efficiency processing and magneto-finishing processing technology. |
