| 目的 研究瓦楞机支撑侧板在复杂应力作用下的动态特性。 方法 通过 Pro / E 建立瓦楞机支撑侧板模型,运用有限元分析方法对侧板原结构和优化后的结构进行模态分析,并将前后模态分析结果进行对比。 结果 得出了侧板原结构和优化后的结构的前 5 阶固有频率和模态振型图,分析结果显示侧板原结构产生了扭转振动、摆动和弯曲变形,优化后的侧板结构变形减小,刚度增加,固有频率提高约 25% ,质量减轻约 83 kg。 结论 侧板结构优化是比较合理可靠的,可以为结构优化设计提供一定的参考依据。 |

| Objective To study the dynamic characteristics of the support panel for corrugator under complex stress. Methods A model was built for the supporting panel for corrugators using Pro / E, modal analysis was conducted for the original structure and the optimized structure of the support panel using the finite element analysis, and the results of modal analysis before and after optimization were contrasted. Results The five-order natural frequencies and mode shapes were obtained for the original structure and the optimized structure of the panel. The analysis results revealed that the original structure of the panel suffered from torsional vibration, swing and bending deformation, while the optimized panel structure showed lower degree of deformation and increased stiffness, with about 25% increase in the natural frequency and about 83 kg loss in the weight. Conclusion The structural optimization of the panel was reasonable and reliable, which provides reference for structural optimization design. |
