A method of manufacturing and installing a rudder blade

Abstract

The invention relates to the field of ships, and discloses a method for manufacturing and installing rudder blades, comprising the following steps: selecting a rudder type, determining a rudder blade size scaling table, determining an actual rudder blade size table, manufacturing the rudder blades, and installing the rudder blades. Wherein, the step of determining the rudder blade size scaling table includes obtaining the relative length value x / b of each point and the relative half-width value y / b of each point to form the rudder blade size scaling table; in the step of determining the actual rudder blade size table Including multiplying the length B of the rudder blade with the relative length value x / b and the relative half-width value y / b of each point in the rudder blade size scaling table to obtain the actual point rudder length value x' of each point And the actual rudder blade half-width value y' constitutes the actual rudder blade size table. The manufacturing installation method of rudder blade of the present invention can obtain the actual rudder blade size table of the rudder blade of different rudder blade length B according to the rudder blade size scaling table, and it is suitable for manufacturing the rudder blade with the same rudder type but different sizes, to simplify Ship manufacturing process, improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for manufacturing and installing rudder blades. Background technique [0002] The rudder blade is the body that generates the rudder force, and it is the most commonly used important component for large ships to control the course. The quality of a rudder blade's handling performance requires a lot of hydrodynamic calculations and tank test verification, which takes a lot of time and cost to complete. [0003] The rudder blades of existing ships are usually designed and manufactured according to the design and manufacture method of one ship, one rudder, that is, every time a ship is manufactured, regardless of its type or size, it will be re-manufactured according to the size and type of the ship to match it the rudder blade. Although, this method can obtain rudder blades with good performance. However, the manufacturing method of this kind of rudder blades makes the st...

AI Technical Summary

Problems solved by technology

However, the manufacturing method of this kind of rudder blades makes the staff need to repeatedly design suitable rudder blades every time they produce a ship. Rudder blades are designed and manufactured one by one for ships of the same type of size, so there are problems such as cumbersome process, waste of time and energy, and not conducive to improving production efficiency
