| 摘 要： | 建立了螺杆轴向振动的动力学模型，研究了模型的质量、阻尼、刚度和激励的简化计算方法，通过求解方程和分析，得出结论：当其他参数确定时，螺杆的转动能改变螺杆轴向振动的平衡位置，但不能影响其频率；转速恒定，螺杆轴向振动的振幅和初相角保持稳定；在一定范围内，转速越高（低），螺杆轴向振动的振幅越大（小）。

| Abstract: | The dynamical model of the screw's axial vibration of Vibrated Single-Screw Polymer Mold Extruder was established,and the calculating methods how to predigest the mass,stiffness,damp and excitation were studied,and the conclusion was drawn by means of solving the equation and analysis.When the other parameters were fixed,the screw's rotation can change the equilibrium position of the screw's axial vibration but can not affect its frequency. And the amplitude and original phase angle of the screw's axial vibration keeps stabilization while the screw keeps a stationary rotating speed,and in a certain extent,the higher rotating speed,the bigger amplitude of the screw's axial vibration,the lower rotating speed,the smaller amplitude of the screw's axial vibration. |
