812 接触回転系におけるパターン形成現象 : エネルギー指数を用いた効果的な設計法

概要

論文の詳細を見る
While the contact rotating systems are operating, the periodic polygonal deformation patterns are often formed on the peripheral surfaces of rolls due to viscoelastic deformation, deformation, cutting, grinding, wear and so on. Such phenomena are caused by the unstable vibration generated in the time delay system. The authors apply the simplified method suggested in the previous reports to analyze the patter formation phenomena to the three-stage-roll model considering the bending deformation of shafts, and formulate a simplified criterion for the stability analysis. In addition, the transfer stiffness coefficient method was applied to the modal analysis and the calculation of characteristic roots to improve the computation efficiency. The validity of the present method is confirmed from the numerical computational results.
