• Systematic Examinations of Vibration Suppression Effects of Dynamic Vibration Absorber Depending on the Design Criteria and Excitation Forms

抄録

As an example of passive vibration control devices, the dynamic vibration absorber installed in the main system of no-damping is considered and the vibration suppression effects for free vibration responses and forced steady-state and nonstationary responses are systematically examined as to the cases in which the device is desighned according to the four typical design criteria, i.e., the conventional frequency shaped response function method (FPT), the linear quadratic optimal control theory (LQC), the minimum variance criterion (MVC) and the eigenvalue optimization criterion (EOC). As a result, the device designed by FPT, LQC and MVC shows almost equivalent vibration suppression effects and has a fairly good robustness, whereas EOC shows the worst effects of all except the settling time of free vibration. As another result, the frequency response evaluation method widely used as the criteria, for example, of transmission loss of noise insulating wall transmission coefficient of silencer or H^∞ control theory turned out to be not necessarily valid especially for the nonstationary excitations.
