Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] see Figure 2 to Figure 5 , the design method of a kind of large ship rudder arm of the present invention, comprises the following steps:

[0035] Step 1, according to the rudder blade design drawing and the rudder blade type value table and marked dimensions on the rudder blade design drawing, draw the contour line of the rudder blade according to the following procedures:

[0036] (1) First draw the center line 100 of the rudder stock, and then draw the center line 200 of the bottom plate of the rudder blade and the center line 300 of the top plate of the rudder blade perpendicular to the center line 100 of the rudder stock respectively according to the dimensions marked on the design drawing of the rudder blade;

[0037] (2) According to the length of the bottom plate of the rudder blade marked on the design drawing of the rudder blade, intercept the front end po...

Abstract

The invention discloses a method for designing a large-scale marine rudder horn. The method includes the following steps that 1, according to design drawing of a rudder blade, a rudder blade offset sheet on the design drawing of the rudder blade and the dimension, a contour line of the rudder blade marked is drawn; 2, a top plate contour line of the whole rudder blade is drawn; 3, according to thedistance from a bottom plate of the rudder blade to the bottom surface of a ship body and a structural form of a ship body stern part, the distance from a top plate of the rudder horn to the bottom plate of the rudder blade is determined, and according to a tabling structure of the rudder blade and the rudder horn, the distance from a bottom plate of the rudder horn to the bottom plate of the rudder blade is determined; 4, stations and station tracks on the bottom plate of the rudder horn and stations and station tracks on the top plate of the rudder horn are drawn; 5, a bottom plate contourline and a top plate contour line of the rudder horn are drawn; and 6, a tail part suspension position and a shape of the rudder horn are determined. According to the method for the designing large-scale marine rudder horn, the designed contour line of the rudder horn is in a good streamline shape and is in natural transition with the line shaped of the rudder blade.

Description

technical field [0001] The invention relates to a design method for a rudder arm of a large ship. Background technique [0002] The course change of a large ship is accomplished by steering equipment, and the rudder is the most commonly used steering equipment. There are many forms of rudders, which can be divided into ordinary rudders, semi-suspended rudders and suspended rudders according to their connection with the hull. The stern line of large ships is generally an open stern frame, so semi-suspended rudders are commonly used. The upper half of the semi-suspended rudder is connected with the rudder arm through the rudder button, and the lower half is suspended. The rudder arm 1 is an arm-shaped member fixed outside the stern of the hull 2. Its upper arm extends into the hull and is firmly connected with the outer plate and structure of the stern of the hull. The lower arm and the rudder knob are connected to the rudder blade 3 match (see figure 1 ). [0003] The ru...
