| 中文摘要: |
| 利用有限元分析软件ANSYS建立CTP成像滚筒的几何模型与有限元模型，选择接触单元模拟版材和滚筒表面之间的关系，以滚筒本体、滚筒与版材组合以及对滚筒内部吸真空的3种组合下进行有限元静力分析，获得滚筒自身变形对版材影响的大小，以及滚筒内抽吸真空对版材和滚筒变形的影响。结果表明，3种情况下滚筒和版材的最大变形量及位置均有所不同。其中，吸真空组合分析说明，版材在与滚筒表面密合状态下变形情况随从滚筒，滚筒表面的导槽对版材变形会产生一定影响，真实反映了工作状态，研究结果可以为CTP成像滚筒的设计与优化提供理论依据。 |

| Geometric model and finite element model of CTP imaging drum are established using finite element analysis software ANSYS. The relationship between plate and roller surface was simulated by selecting contact element. The static characteristics of combination among drum body, roller and plate as well as additional vacuum suction inside cylinder were analyzed. The results showed that the maximum deformation and location of roller and plate are different in the three cases. The analysis of vacuum suction combination showed that in the condition of the combination between plate and roller surface, the size of deformation is based on the roller and the guiding groove on roller surface affects the deformation of piate, which in reality reflects the working state. The purpose was to provide theoretical basis for design and optimization of CTP imaging drum. |
