基于ANSYS Workbench的烟包机推包机构模态分析

Modal analysis for pushing mechanism of tobacco packing machine based on ANSYS Workbench

烟包机是包装行业中重要的包装机器之一,随着们对香烟需求量的增加,香烟生产厂对烟包机的速度要求越来越高。由于振动会造成结构的共振或疲劳,从而破坏结构,所以针对烟包机推包机构高速运动时容易产生振动的问题进行研究,分析推包机构主要部件平面沟槽凸轮,利用Pro/E建立平面沟槽凸轮实体模型,然后导入Workbench软件中进行自由模态分析和约束模态分析,求出其振动特性,为推包机的优化设计提供了必要依据。

Tobacco packing machine is one of the important packaging machines in packing industry.Along with the increase of demand for cigarette,the demand for speed of the machine in cigarette factories is increased.Since the vibration may cause structure resonance or fatigue,the structure may be destroyed,in this case the vibration problem caused by high-speed pushing mechanism of tobacco packing machine is studied,the plane groove cam which is the main part of pushing mechanism is analyzed.With Pro/E software the solid model of plane groove cam is built,then it is transmitted into Workbench software,in which free modal analysis and the restraint modal analysis are completed.From the analysis result,the vibration performance is obtained,which provide an essential basis for optimization design of the pushing mechanism.
