A Study on Optimum Design to Suppress Pattern Formation Phenomena of Rolling Contact Systems Caused by Viscoelastic Deformation.

造纸机的辊套胶在长期运行后，经常会变形成一定的凸多边形。这种现象称为花纹形成现象，它导致机器的强烈振动，并造成纸张和机器的损坏。在这项研究中，作为抑制由橡胶的粘弹性变形引起的花纹形成现象的对策，通过理论和实验分析来检查外部阻尼、转速变化、动力吸收器和辊之间的直径比的影响。发现每种技术都可以抑制图形形成现象，并提出了抑制图形形成现象的最佳设计。

The roll covering rubber of a paper making machine is often deformed into a certain convex polygon after the long operation. The phenomena are called pattern formation phenomena which lead to strong vibration of the machine, and cause the damage of the paper and the machine. In this study, as the countermeasure to suppress the pattern formation phenomena caused by the viscoelastic deformation of the rubber, the effect of the external damping, variation of the rotating speed, dynamic absorbers and diametral ratio between the rolls are examined by theoretical and experimental analysis. It is found that the pattern formation phenomena can be suppressed by each technique, and the optimum design to suppress the pattern formation phenomena is suggested.
