Abstract

In order to prevent the pattern formation phenomena caused by the unstable vibration generated in time-delay systems, an optimum design method of dynamic absorber is formulated for contact rotating systems of viscoelastic, grinding and wear types with single-degree-of freedom. In addition, as a key tool for the optimum design, a very efficient and accurate method of stability analysis is newly developed for the pattern formation phenomena generated in contact rotating systems. In the formulation of the optimum design method, the stabilization of the system under the worst conditions is targeted. As a result, the limit of applicability of the dynamic absorber is clarified and it becomes possible to stabilize the system under ordinary conditions by the dynamic absorber without knowing the details of viscoelastic, grinding and wear characteristics of the system.
