中文摘要:
      目的 提出一种印刷滚筒的新型结构设计方法,并对其进行挠曲变形分析。方法 从印刷滚筒结构设计层面出发,研究常规印刷滚筒挠曲变形规律,提出变刚度印刷滚筒结构设计方法,对比分析常规印刷滚筒与变刚度印刷滚筒的挠曲变形和质量变化。结果 1.85 m和1.05 m的常规印刷滚筒最大挠曲变形值分别为0.052 mm和0.0181 mm,考虑重力之后的挠曲变形增幅分别为49.4%和52.5%,1.85 m和1.05 m的变刚度印刷滚筒相比常规印刷滚筒挠曲变形降幅分别为23%和21%,质量降幅为16.3%和9.9%。结论 变刚度印刷滚筒避免了常规印刷滚筒铸造缺陷对印刷性能的限制,在明显降低挠曲变形的同时,滚筒质量也能得到较好的控制。
英文摘要:
      The work aims to propose a new type of structure design and study the flexural deflection of printing cylinder. From the structure design of printing drum layers, rules on flexural deflection of regular printing cylinder were studied. The structure design method of variable stiffness printing cylinder was presented. The deflection and the quality changes between regular printing cylinder and variable stiffness printing cylinder were analyzed. The maximum deflection of 1.85 m and 1.05 m regular printing cylinders were 0.052 mm and 0.0181 mm, respectively; the growth of deflection was 49.4% and 52.5%, respectively. After considering gravity, the decline of deflection of 1.85 m and 1.05m variable stiffness printing cylinder was 23% and 21%, respectively. Compared with regular printing cylinder, the decline of quality was 16.3% and 9.9%. Variable stiffness printing cylinder can avoid the casting defect of regular printing cylinder on restriction of printing performance, and control quality of cylinder effectively, while significantly reduce the deflection.
