Pattern formation phenomena often occur in contact rotating systems. A prevention method by using dynamic absorbers was suggested and an optimal design method of the dynamic absorbers was formulated in the previous reports. However, much computation time is required to establish the optimal parameters for multi-degree-of-freedom systems since design variables increase. The authors suggest an efficient design method of dynamic absorbers, in which the dynamic absorbers are individually designed one by one for each mode. The effectiveness of the present method is verified from the results of numerical computations for a five-degree-of-freedom system as an example.
