| 摘 要： | 传动链刚度是机床中滚珠丝杠驱动进给系统建模和辨识的关键。该文基于静力学平衡方程和变形协调条件,建立了新的丝杠传动链静刚度模型;结合丝杠两端边界条件,求解其集中载荷过程激励的二阶波动方程频域Fourier变换,建立了分离参数动刚度模型,统一了2种模型。静刚度模型、动刚度模型低频特性与静刚度模型的一致性、动刚度模型的高频特...

| Abstract: | The mechanical stiffness is the key to modeling of ball screw drive systems in machine tools.This paper presents a static stiffness model of a ball screw drive system based on the static equilibrium and the deformable coordination.The Fourier transform of the second order wave equation in the complex frequency domain for the exciting of a concentrated load was used in a distributed parameter dynamic model of the ball screw with different boundary conditions on the two ends.This static stiffness model was ve... |
