| 目的 研究圆柱壳减振装置在货物包装中的振动特性。方法 利用有限元软件ABAQUS对圆柱壳减振装置的材料属性进行精确建模，使用模态分析方法得到圆柱壳减振装置在径向、横向和周向的模态振型云图，以及所对应的固有频率，在此基础上研究减振装置材料的弹性模量和货物重力对减振装置振动特性的影响。结果 减振装置的自振频率随着材料弹性模量和货物重力的增加而显著提高，结合具体实例将减振装置在无重力挤压下的最低自振频率由原先的11.25 Hz提高到19.51 Hz，在重力挤压下由19.51 Hz提高到31.24 Hz，避免了共振的发生。结论 通过改变减振装置材料的弹性模量可以有效避开外部激励源的谐振载荷频率范围。 |

| The work aims to study the vibration characteristics of the cylindrical vibration absorber in cargo packaging. The material properties of the cylindrical vibration absorber were accurately modeled with the finite element software ABAQUS. The nephogram of the modal vibration type of the cylindrical vibration absorber in radial, transverse and circumferential directions and the corresponding inherent frequency were obtained by the modal analysis. Based on that, the influence of the elastic modulus and weight of the cargo on the vibration characteristics of the vibration absorber was studied. The natural vibration frequency of the vibration absorber was significantly improved with the increase in the elastic modulus and the weight of the cargo. In combination with the specific examples, the minimum natural vibration frequency of the vibration absorber without gravity extrusion was increased from the original 11.25 Hz to 19.51 Hz, and increased from 19.51 Hz to 31.24 Hz under gravity extrusion, so as to avoid the resonance. By changing the elastic modulus of the vibration absorber, the resonant load frequency range of the external excitation source can be effectively avoided. |
