摘要
笔者利用分布切削力的特性建立的一种磁滞动力学微分-积分方程为例,提出了一种新的稳定性判别法,给出动力学方程渐近稳定条件及稳定性判别理论,通过计算特征方程的辐角变化量来判别方法的稳定性。该方法计算简单,可以成为切削加工的稳定性理论研究的一种新判别方法。
This paper proposes a new stability criterion method, based on a hysteresis dynamic differential-integral equation derived from using properties of distributed cutting force. The paper offers asymptotically stable conditions for Kinetic equation and stability criterion theories and identifies stability of systems by calculating change in argument of characteristic equation. The method features an easy operation and promises as a new criterion method for theoretical study of stability of cutting process.
