Abstract

The invention discloses an optimized design method for a ship anchoring machine seat. The method comprises the following steps of: determining the appearance and the size of the machine seat according to basic design parameters of an anchoring machine, and constructing a three-dimensional model of the machine seat; constructing a three-dimensional entity finite element model and a topology optimization model of the machine seat, and performing topology optimization design under working condition of supporting a load; determining at least one preferable scheme of the machine seat according to a topology optimization result; constructing a simplified finite element model of the preferable scheme by using a shell unit, performing size optimization design under the working condition of supporting the load, and determining an optimal machine seat structure; and finally performing structural design on the optimal machine seat structure, and determining a final machine seat model, namely the optimal shell unit machine seat structure is an actual entity machine seat structure. The optimal topological structure of the machine seat can be determined in a concept design stage, and a machine seat structure which meets certain intensity and rigidity and is the lightest can be determined in the subsequent detail design stage.

Description

technical field [0001] The invention belongs to the field of mechanical design, and relates to a design method of a ship windlass, in particular to an optimal design method of a ship windlass base. Background technique [0002] As an important part of modern ship deck machinery, the windlass plays the role of anchoring, anchoring, mooring and cable, and its reliability characteristics play a decisive role in keeping the ship's position unchanged, braking the ship in an emergency, and making the ship safe from the dock . In the process of developing new windlass products, most manufacturers use classic empirical formulas to design windlass components, and can only use a higher safety factor to ensure its safety, making the size and weight of the anchor chain wheel larger and larger , there is a large difference between the theoretical carrying capacity and the actual carrying capacity. This method has defects such as narrow application range, low analysis accuracy, small amo...
