因为球头铣刀动力学模型为常系数非齐次线性微分方程,用数值方法对此方程进行近似计算求解,对于节点处的离散方法不同,算法(Simpson方法、Eluer方法、Runge-Kutta方法等)不同,对于它们的精度、方程求解的收敛性及稳定性进行了分析与比较。本文对常见的几种计算机仿真算法进行了讨论,对于球头铣刀动力学模型仿真算法的选择有一定参考意义。 Because the dynamic model of the ball end mill is a constant coefficient inhomogeneous linear differential equation, this equation is approximated and calculated by numerical method. For the discrete method at the node, the algorithm (Simpson method, Eluer method, Runge-Kutta method, etc.) ), Their accuracy, convergence and stability of equation solving are analyzed and compared. In this paper, several common computer simulation algorithms are discussed, which is of some reference significance to the choice of the simulation algorithm of the dynamic model of the ball mill.
