Finite Element Analysis and Topology Optimization Design of Anchor Mooring Winch Support Bracket

Abstract The weight of the deck machinery greatly affects the position of the small ship’s center of gravity so that it also affects the stability of the ship. Therefore, it is necessary to conduct optimization studies to reduce the weight of ship deck machinery, especially anchor mooring winch, by reducing the weight of ship deck machinery will lower the position of the center of gravity of ship so that can improve ship stability. This paper presents the effects of a topology optimization examination based on the finite element evaluation on anchor mooring winch support bracket using the SolidWorks Simulation module. The main intention to examine is to optimize the general weight of the anchor mooring winch support bracket via way of means of thinning specific regions of the anchor mooring winch support bracket in keeping with the calculated minimum strain energy. The topology optimization algorithm that is used in the current study gives an optimal structural shape of the support bracket of the anchor mooring winch with the largest stiffness, considering the given quantity of mass so that it will be eliminated from the preliminary layout space. The complete sequence of steps for carrying out the topology control optimization study is shown, taking into account the constraints arising from the construction features and the method of manufacturing the support bracket of the anchor mooring winch. The layout became carried out, and the effects have been provided via way of means of evaluating the preliminary version and the optimized version. As the result of topology optimization study, its stress was increased by about 4MPa and mass was reduced by about 15kg in comparison with the initial design.
