Lightweight design method of windlass reel device

Abstract

The invention discloses a lightweight design method for a drum device of anchor and mooring equipment. The drum device comprises a drum body, a drum shaft, a right side flange, a mesh tooth block, a middle flange, a left side flange, a hub and the like. The design method comprises steps as follows: key parameters of the drum device are extracted, and a three-dimensional parameterized model is established; a virtual prototype of the complete machine is constructed, a mooring rope retracting and releasing process of the drum device of the anchor and mooring equipment is simulated and analyzed according to dynamics simulation, and required load is extracted; parts of the drum device are subjected to finite element analysis; feasibility of optimization measures and computational formulae is theoretically analyzed, the model is optimized, and the drum device, with the best structural size, of the anchor and mooring equipment is determined. According to the method, a conventional extensive type experience design is changed, scientific part strength computation and optimization design is performed with the method combining theoretical analysis, virtual prototype simulation and finite element analysis, so that the technical indexes such as performance, weight and the like of the drum device of the anchor and mooring equipment meet the international advanced level.

Description

technical field [0001] The invention relates to a lightweight design method, in particular to a lightweight design method for an anchor windlass reel device. Background technique [0002] At present, the shipbuilding industry technology is constantly developing towards "green ships". The anchor winch products, one of the important supporting equipment for ships, should also develop in the direction of energy saving and environmental protection in technology: that is, reducing the overall weight and saving materials, reducing energy consumption, improving transmission efficiency, improving Environmental index reduces vibration and noise pollution. With the rapid development of the shipping industry, the tonnage of ships is getting larger and larger, and the load on the anchor winch is also increasing. At present, compared with foreign products, my country's anchor winches obviously have large volume, heavy weight, and overall The efficiency of the machine is low and other def...

Problems solved by technology

With the rapid development of the shipping industry, the tonnage of ships is getting larger and larger, and the load on the anchor winch is also increasing. At present, compared with foreign products, my country's anchor winches obviously have large volume, heavy weight, and overall The efficiency of the machine is low and other defects. As the key component of the anchor winch, the drum is currently designed mainly on the basis of empirical formulas. Due to the lack of accurate strength calculations, only a high safety factor can be used to ensure its safety performance. This makes the drum size and weight are getting bigger and bigger
