| 目的 研究柔性杆件从实际工况开始，随着工作转速的提高对开盒机动态性能和开盒角度的影响。方法 利用 SolidWorks 建立了开盒机的三维实体模型，通过导入 ADAMS 建立开盒机的纯刚体模型，利用 Ansys 对杆件进行柔性化处理，生成模态中性文件，将其导入纯刚体模型中建立开盒机的刚柔耦合模型，并进行动力学仿真分析，仿真结束后将载荷文件导入 Ansys 进行关键部件的应力分析。结果 得到了开盒杆相对吸盒杆的最大转角和关键部件的受力，得出工作转速 340 r/min 为此开盒机的极限转速，且通过加强杆件的强度可以使开盒机提速运行，但必须进行全面的动态性能研究和优化。结论 采用刚柔耦合分析方法可以更真实地仿真开盒机的实际运动状态，尤其是在工作转速较高阶段，且相对于纯刚体模型，可以更全面地分析开盒机的动态性能。 |

| The work aims to study the effect of flexible rods on the dynamic performance of the box opener and the opening angle of the box with the increase of the working speed starting from the actual working conditions. SolidWorks was used to build the 3D solid model of the box opener. The pure rigid body model of the box opener was built by importing ADAMS, and the rod parts were flexibly processed by Ansys to generate the modal neutral file, which was then imported into the pure rigid body model to establish the rigid-flexible coupling model of the box opener for the dynamic simulation analysis. After the simulation, the load file was imported into Ansys for stress analysis of key components. The maximum corner of open box rod relative to suction box rod and the stress of the key components were obtained. It was concluded that the working speed 340 r/min was the limit speed of the box opening machine. By strengthening the strength of the rod parts, the box opener could run at a higher speed, but it was necessary to carry out comprehensive dynamic performance research and optimization. The rigid-flexible coupling analysis method can be used to more realistically simulate the actual motion state of the box opener, especially in the stage of a higher working speed; and compared with the pure rigid body model, it can analyze the dynamic performance of the box opener more comprehensively. |
