Anchor windlass base structure optimization method

Abstract

The invention relates to an anchor windlass base structure optimization method. The method is characterized by comprising the following steps: S1, establishing an anchor windlass base model; s2, carrying out finite element analysis; s3, carrying out topological optimization and analysis structure comparison; s4, creating an optimization model; and s5, performing comparative analysis. On the basisof mechanical analysis of an original base model, topological optimization is conducted on a base through software, different optimization parameters are set, space materials designed for the originalbase model are rearranged, and therefore a brand-new optimization structure is obtained, and mechanical property comparative analysis is conducted on the optimized base model and the original model;the result can be obtained through comparative analysis of the base structures before and after optimization; after optimization, the overall weight of the base is reduced by 5.78%, the maximum totaldisplacement is reduced by 0.174 mm, meanwhile, the strength, dynamic characteristics and vibration resistance of the base are improved, the mechanical property of the base is enhanced, and the economical efficiency and safety of base design are met.

Description

technical field [0001] The invention relates to the field of anchor winch base design, in particular to a structure optimization method for anchor winch base. Background technique [0002] "Green ship" is the development direction of the current shipbuilding industry, and the anchor winch, as an important supporting equipment for the ship's mooring system, is an indispensable deck machinery for ships, and is also technically developing in the direction of economy, energy saving and green environmental protection. The windlass base is the link connecting the hull structure and the windlass body, and is an important bearing part of the windlass. The reliability of its structural design is extremely critical to ensure the safe operation of the windlass and the ship. Traditionally designed windlass foundations mainly rely on empirical formulas to design, lack accurate strength calculations, and rely on a high safety factor to ensure their safety performance, making the foundatio...
