回転円板振動に与える腰入れ効果の基礎的研究

抄録

Distributed tensioning in a wide range usually performs on a tipped saw. We studied this distributed tensioning effect analytically and experimentally using normal and tensioning disks. The following conclusions were reached. (1) Residual stress due to tensioning was measured. Residual stress distribution could be calculated by Gaussian-type isotropic additional stress. (2) Natural frequency change by tensioning treatment was calculated by the energy methed and was in good agreement with measured frequencies. (3) A backward traveling wave of the second mode determined the critical rotating speed, and the rotating speed domain above this critical point was unstable. This phenomenon was confirmed by transfer function measurment. (4) The tensioning effect increased natural frequencies and expanded the stable domain.
