Anchor-pulling test method for simulating anchor recess of real ship

Abstract

The invention provides an anchor-pulling test method for simulating an anchor recess of a real ship. The method is characterized by comprising the following steps of 1, drawing an actual shape of the anchor recess according to a location dimension of a design drawing and a lines plan of a ship hull plate; 2, simulating multiple states of an anchor during dropping, judging whether the anchor is collided with a bulbous bow plate or not, and according to the judgment, determining the position of an outlet point of a hawse pipe; 3, simulating a state of the anchor when an anchor rod just enters the hawse pipe in a lifting process, judging whether an anchor sticking phenomenon occurs or not, and according to the judgment, determining an included angle between a central line of the hawse pipe and a vertical direction; and 4, simulating a state of the anchor during lifting in the anchor recess, and according to the state, determining the length of the hawse pipe, an angle of an anchor recess backboard, and the height of an anchor mouth. According to the method, by statically simulating an anchor-pulling test process on design software of a computer, a few defects of anchor recess design can be discovered in advance and then corresponding modification is performed, so that repeated modification of the hawse pipe and an anchor rack in an anchor-pulling test is avoided and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of ship anchor pulling tests, in particular to an anchor pulling test method for simulating a real ship anchor hole. Background technique [0002] The setting out of the anchor hole and the test of the anchor wooden formwork have always been a difficult point, and it is also a very important link. Through the anchor test, we can find out the unreasonable design and correct it to achieve the effect that meets the site requirements. At present, we do not have a complete set of anchor hole lofting and anchor pulling test process. In the past, the traditional method generally goes through lofting first, and then nails the model according to the proportion to carry out the anchor pulling wooden formwork test to check whether the anchor can be received smoothly. Put it, and the three points are close to each other. However, the anchor itself has complexity, uncertainty, and some unreasonable factors in the design...

AI Technical Summary

Problems solved by technology

However, the anchor itself has complexity, uncertainty, and some unreasonable factors in the design stage, so repeated revisions often occur in the anchor pull test, and the anchor chain barrel and anchor frame of the anchor pull test are very difficult. Bulky, so repeated revisions are not only a lot of work, but also difficult
