摘要/Abstract

摘要： 为了实现叶片磨削过程中磨削力的精确测控，针对磨削力变化的高动态特性，提出了采用相互正交的独立弹性元件测量三向正交磨削力的方法，并设计出电阻应变式三维动态磨削力测量平台.通过运用材料力学相关公式进行数学推导和Workbench有限元仿真及实际测试实验验证了其性能.实验表明上述方法有效解决了测力仪固有频率与灵敏度之间的矛盾，并在结构上降低了各向磨削力测量之间的向间耦合程度，为实现高频磨削力的实时精确检测提供了技术保障.

Abstract: In order to achieve the accurate measurement and control of grinding force in the blade grinding process， a new measurement method of three-dimensional and orthogonal grinding force with mutual orthogonal and independent elastic elements was put forward， and a three-dimensional grinding force measurement platform of resistance strain was designed based on the high dynamic characteristics of grinding force. The performance of the measurement platform was verified through the mathematical derivation with the related formulas of material mechanics， the finite element simulation with Workbench and the actual testing experiments. The results showed that the above methods can effectively alleviate the dynamometer’s inherent contradiction between its natural frequency and sensitivity， and significantly reduce the measurement platform’s coupling degree among the grinding force measurements in different directions， which may provide technical support for achieving the real-time accurate detection of high frequency grinding force.

Key words: blade grinding, grinding force, dynamometer, elastic element, modal testing
