Dynamic vibration absorber (DVA) for reduction of flywheel vibration was developed. The optimum tuning frequency and damping ratio of the absorber in the damping system were derived by multi-variable multi-mutation adaptive genetic algorithm (MMAGA). Then mathematical formulae of the optimal parameters were obtained by regression analysis. The rationality of design and damping performance of the DVA were verified by experimental testing and numerical simulation. It is concluded that the optimum absorber can reduce the vibration response of the flywheel. MMAGA was suitable for calculating optimum parameters of the absorber efficiently. Simulation and test validates that the DVA can effectively depress the vibration of the flywheel.
