Abstract:

In this paper, the effect of the centrifugal force cutting temperature stresses and the position of roll tensioning on the dynamic behavior and the critical speed of the circular saw blade is researched with the nonlinear and the matrix perturbation theories. The optimum position of roll tensioning is analyzed under the action of the centrifugal force and cutting temperature stresses. The effect of tamped radius on the optimum position is also analyzed.

Key words: Circular saw blade, Roll tensioning treatment, Critical speed
