| 目的 验证封口机构主要受力零部件转轴满足实际工况的需求。方法 基于某袋成型包装机的整体布局设计、封口机构的方案设计以及理论计算，完成对相应封口机构的三维建模，再利用Ansys Workbench对其进行静力学分析、模态分析，以及使用疲劳分析软件nCode DesignLife进行疲劳分析。结果 转轴表面所受应力最大为29.94 MPa，其固有频率均大于1246.6 Hz，同时转轴绝大部位的疲劳次数大于1.127×108。结论 证明符合理论设计的要求，在实际工况条件能正常工作且不发生共振及安全疲劳，由仿真分析可对可能发生疲劳破坏的位置进行预测。 |

| The work aims to verify that the main stressed component (rotating shaft) of the sealing mechanism meets the needs of the actual working conditions. Based on the design of the overall layout for a bag forming packaging machine and the design scheme and the theoretical calculation of the sealing mechanism, the 3D modeling of the corresponding sealing mechanism was completed. Then, the static analysis and modal analysis thereof were carried out with Ansys Workbench and the fatigue analysis was conducted by fatigue analysis software nCode DesignLife. The maximum stress on the surface of the rotating shaft was 29.94 MPa, the natural frequency was more than 1246.6 Hz, and the life of most parts of the shaft was more than 1.127×108. The results show that it can meet the requirement of theoretical design, work normally in the actual working conditions, and will not produce resonance and safety fatigue. The location of fatigue failure can be forecasted according to the simulation analysis. |
