在建立外圆磨削过程动力学模型的基础上，应用矩阵摄动理论论证了砂轮与工件接触刚度与工件颤振频率之间的关系，探讨了径向磨削力与接触刚度之间、砂轮转速与径向磨削力之间的关系，得出了砂轮转速与工件颤振频率之间具有相对应的关系。
Based on the establishment of the dynamic model of the cylindrical grinding process, the relationship between the contact stiffness of the grinding wheel and the workpiece and the chatter frequency of the workpiece is demonstrated by the matrix perturbation theory. The relations between the radial grinding force and the contact stiffness, Speed and radial grinding force between the relationship between the wheel speed and the workpiece flutter frequency has a corresponding relationship between.
