印铁机压印滚筒参数优化分析

摘要

压印滚筒是印铁机关键部件，其工作性能直接影响印品最终的品质，传统的设计方法不能平衡滚筒的变形、应力和动态特性之间的关系。运用 ansys workbench对压印滚筒进行参数优化设计，在保证滚筒的受力和动态性能得到改善的同时，减小滚筒的最大变形。优化结果表明：通过截面尺寸的改进，在保证变形最小的前提下，应力得到了减小，固有频率得到了提高。优化结果提升了压印滚筒的综合工作性能，为生产实践提供了理论支持。%the impression cylinders are the key part of iron printing machine. Its working properties has a direct influence on the final products. The relationship among deformation, stress and dynamical properties can ont be balanced in the traditional de-sign. ANSYS workbench is applied to the parameter optimization of the impression cylinder and improvement of the stress and dynamical properties, so that its max deformation is decreased. The optimization results shows: under the condition of keeping cylinder minimal deformation value, through improving the cross dimension, its stress is greatly lowered, the inherent frequen-cy is raised and the synthesis properties of the impression cylinder is improved greatly. The theorefical support is provided for the practice.
