The invention relates to the technical field of lubricating oil analysis and detection, in particular to a device and a method for separating abrasive particles in lubricating oil based on surface acoustic waves. The advantages of high energy density and easiness in integration of surface acoustic waves are fully utilized in combination with a micro-flow channel of a special geometric shape processed by a soft lithography technology, thereby realizing on-line continuous separation of the abrasive particles in the lubricating oil, and laying a foundation for precise detection of the abrasive particles. The separation device and method omit the structures of a physical filter screen and the like, avoid dirty blockage, and have a high integration degree and a good on-line separation effect. 本发明涉及润滑油分析检测技术领域，具体涉及种基于声表面波的润滑油中磨粒分离装置及方法。本发明充分利用声表面波能量密度高、容易集成等优点，又与通过软光刻技术加工特定几何形状的微流通道相结合，实现了润滑油中磨粒的在线连续分离，为磨粒精准检测奠定了基础。本分离装置和方法取消了物理滤网等结构、避免了脏堵，并且该装置和方法集成度高、在线分离效果好。
