造纸机中较光滑的轧辊的橡胶表面在高夹紧力和高工作速度的情况下变形为一定的凸多边形，这些轧辊相互粘弹性地旋转。多边形变形逐渐发生，导致机器强烈振动。本文描述了该系统的模型，该模型将这种振动现象视为时滞不稳定，并对这种现象进行了理论分析。我们还进行了一个实验，以确定在分析模型中使用的参数。从试验结果可以看出，橡胶的变形恢复特性是时间相关的。数值计算结果与机器实际结果吻合较好。
The rubber surface of a smoother roll in a paper making machine is deformed into a certain convex polygon at a high nip force and a high operating speed of the rolls rotating in contact with each other viscoelastically. The polygonal deformation occurs gradually, which leads to strong vibration of the machine. This paper describes the model of this system, which treats this vibration phenomenon as instability due to a time lag, and a theoretical analysis of this phenomenon. We also conducted an experiment to identify the parameters for use in the analytical model. From the test results, we found that deformation recovery characteristics of the rubber are time-dependent. The numerical results showed good agreement with actual results from machines.
