| Research Abstract |
The dynamnic characteristics of and the control methods for a composite circular saw were investigated. The in-plane stresses, natural frequencies, and modes of the composite saw were analyzed theoretically, considering the rotation and frictional heat due to cutting, and the electric voltage applied to the actuator. Numerical calculations for the results were performed to investigate the effects of parameters of the voltage on the natural frequencies. As a result, the effects of cutting heat on the stability of the saw were found qualitatively and quantitatively, as well as the effets of parameters for voltage application to multiple annual domains on the natural frequencies. Futhermore, the optimization problem that maximizes the critical natural frequency with respect to the parameters were solved.
