摘　　要：根据等截面梁横向振动理论,建立了正交车铣加工细长杆的动力学模型,并根据车铣切削力的特点,建立了切削力的简化模型。分析了强迫振动的动力学响应以及振动过程中切削厚度变化对强迫振动的影响,并利用Matlab软件对其进行了模拟。模拟结果表明,在正交车铣加工细长杆过程中,振动系统可以对强迫振动起到一定的抑制作用。According to horizontal vibration theory of beam of u- niform section,the kinetic model of the orthogonal turn-milling slender rod is presented,and according to the peculiarity of the turn-milling cutting force,the simplify cutting force model is presented.The kinetic response of the forced vibration and the impact of the forced vibration caused by the variety of cutting thickness are studied,and on the basis of Matlab soft the forced vibration is simulated.The simulative results indicate that in the process of the slender rod machining by orthogonal turn-milling the vibration system can restrain the forced vibration.
