| 中文摘要: |
| 目的 在考虑轴承支承刚度的情况下， 对橡皮滚筒进行模态分析和谐响应分析。方法 采用有限元分析软件Ansys对橡皮滚筒进行有限元建模。结果 分析得出其前五阶模态振型和固有频率， 以及轴承支承刚度对橡皮滚筒固有频率的影响， 通过谐响应分析得出橡皮滚筒在载荷冲击下的位移频率响应曲线。结论 分析结果表明， 该型曲面胶印机橡皮滚筒动态特性良好， 可有效保证印刷质量。 |
| 英文摘要: |
| This paper conducted a modal analysis and a harmonic response analysis on the blanket cylinder in consideration of the bearing stiffness. A finite element model of blanket cylinder was built by applying the finite element analysis software Ansys. The first five-order modal shape and the inherent frequency were obtained by the analyses and the influence of bearing stiffness on the inherent frequency was further analyzed. The frequency response curve of the amplitude under load impact was worked out through the harmonic response analysis. These analytical results above showed that the dynamic characteristics of blanket cylinder were fine and the printing quality can be assured. |
