摘要: 首先,提出了一种新型的机械式螺杆轴向振动挤出成型装置,分析了螺杆轴向振动的工作原理;其次,基于包络线理论,导出了凹凸激振曲面的数学模型,据此建立了螺杆轴向振动挤出成型装置的三维模型;然后,基于受力分析,建立了螺杆轴向振动物理模型,并对关键参数的求解进行理论推导;最后,运用 ADAMS 软件对螺杆轴向振动挤出成型装置的振动特性进行动力学仿真. 仿真结果表明,该振动挤出成型装置的振动波形符合规定的简谐振动规律,波形失真度小,振动较为稳定,说明该装置是可行和有效的.

Abstract: In this paper,first,novel mechanical principle-based extrusion equipment with axial screw vibration is designed,and the principle of the axial screw vibration is analyzed. Then,according to the theory of envelopes,the mathematical equations of the undulant vibration surface are established,and a 3D model of the extrusion e-quipment is constructed. Moreover,by the force analysis of the vibration parts,a physical model describing the screw vibration is established,and the key parameters are theoretically inferred out. Finally,in ADMAS environ-ment,a dynamic simulation of vibration characteristics of the extrusion equipment is carried out. The results show that the designed extrusion equipment exhibits a simple harmonic vibration waveform with small distortion and high stability,which means that the equipment is feasible and effective.

Key words: axial vibration, extrusion molding, ADAMS, dynamic simulation, vibration characteristic
