| Abstract: |
| Improving the working stability of impression cylinder is a critical factor in the process of high-speed press design. Modal test and axial channeling analysis was carried out on the impression cylinder with the help of the pulse test system. Modal parameters of cylinder were obtained and the weak links of the cylinder in actual condition were put forward. The causes of excessive vibration of impression cylinder were analyzed in detail by using combination of theory and practical test methods, which solved the problem of printing press in actual production and provided theoretical guidance for dynamic design of high-speed press. |
