| 目的 研究滚切成型装置机架的动态特性， 为分析和评价蔬菜纸面膜成型机的工作性能提供理论依据。 方法 通过 Unigraphics NX 建立滚切成型装置机架的实体模型， 然后导入 Ansys Workbench 进行模态分析， 提取并分析前 6 阶固有频率与振型变化。 结果 滚切装置机架的最小固有频率为334.74 Hz， 机架最大变形发生在第 4阶振型右支撑板前梁的中间部分。 结论 滚切成型装置机架的激振频率远小于最小固有频率，不会产生共振与严重噪声。 |

| Objective To study the dynamic characteristics of the frame of roll cutting device, and to offer basis for the analysis and evaluation of the work performance of vegetable paper facial mask molding machine. Methods Entity model of the frame was established with Unigraphics NX, and modal analysis was carried out using Ansys Workbench, and then the first six orders of natural frequencies and the variation of vibrational mode were extracted and analyzed. Results The minimal natural frequency of the frame was 334.74 Hz. The Maximal amplitude occurred in the fourth order vibrational mode, which was in the middle of the front-axle beam in the right support plate. Conclusion The excitation frequency of the frame was far smaller than the minimal natural frequency. No resonance phenomenon and severe acoustic noise would occur. |
