Application of Dynamic Vibration Absorber in Flywheel Vibration Control |
| |
| Abstract: | Dynamic vibration absorber(DVA) for reduction of flywheel vibration was developed. Optimum tuning frequency and damping ratio of the absorber in damped system were derived by multi-variable multi-mutation adaptive genetic algorithm (MMAGA). Then mathematical formulae of the optimum parameters were obtained by regression analysis. Validating the rationality of design and verifying damping performance of DVA by simulating and testing. The conclusion showed that the optimum absorber can reduce vibration response of flywheel. MMAGA was suitable to calculating optimum parameters of the absorber efficiently. Simulation and test validated that the DVA can largely depress the vibration of flywheel. |
