我们以前的研究表明，在连杆臂端部和驱动刀的连接处发生了三倍于驱动频率的振动。本文建立了切刀驱动系统的动力学模型。考虑支座的弹性变形，采用Voigt模型给出了支座与支座之间的动力相互作用。该模型通过数值计算模拟了水平惯性力。结果表明，在没有配重的状态下，模拟的惯性力和测量的加速度的时间序列的趋势定性对应。该模型能够预测刀具驱动系统的振动特性。【关键词】刀驱动系统，碰撞振动，动力学模型，Voigt模型，平衡重，惯性力
Our previous study suggested that a vibration, which was three times the driving frequency, occurred at the joint of the link arm end and the drive knife. In this paper, we constructed a dynamic model of the knife driving system. By considering the elastic deformation of the bearing, the dynamic interaction at the joint was given by the Voigt Model. This model simulated the horizontal inertia force by numerical calculations. The results revealed that the tendencies qualitatively corresponded well with the time series of the simulated inertia force and measured acceleration in the state without the balance weight. The model enabled the forecasting of vibration characteristics of the knife driving system.
