In this paper, an anti-vibration optimal design method for bridge wings of bulkers is proposed. In general,bridge wings have disadvantage for its vibration characteristic due to its cantilever like structure. To improve vibration characteristics of the bridge including wing structures, some structural optimization methods can be effective. The research is performed in following processes. First, vibration of the bridge is simulated using finite element method for frequency response problems. Next, based on the vibration analysis, the stiffness maximization optimization problem of wing structure is formulated to raise eigen-frequencies of bridge. Two types of topology optimizations are performed for the optimization problem. Based on the optimal results, two new structures of bridge wing are proposed based on the optimal result. Finally, we confirm the usefulness of the proposed method by vibration analysis of the new bridge wings.
