Embodiment 1

[0024] Such as image 3 As shown, the method for calculating the card-like directrix point of the non-parallel line type includes the following steps:

[0025] S1: Make the first vertical line at the middle position of the first card-like line type 11, and make the tail vertical line at the middle position of the last card-like line type 12;

[0026] Specifically, in this embodiment, there are four card-like line types, which are curve L1, curve L2, curve L3 and curve L4 respectively. In this embodiment, the curve L1 , the curve L2 , the curve L3 and the curve L4 gradually become shorter according to the number of times, wherein the curve L1 is the longest and the curve L4 is the shortest. It should be noted that in this embodiment, the curve L1 is the first card-like line type 11 , and the curve L4 is the tail card-like line type 12 . The four card-like line types can be regarded as the section line types of the curved plate at the corresponding rib position. In this embod...

Abstract

The invention relates to a non-parallel line type card sample quasi-line point solving method. The method comprises the following steps: S1: making a head vertical line through a head card sample line type, and making a tail vertical line through a tail card sample line type; S2: intercepting a set length on the head vertical line to create a head card sample rod corresponding to the head card sample line type, and intercepting a set length on the tail vertical line with the intersection point of the tail card sample line type and the tail vertical line as a starting point to create a tail card sample rod corresponding to the tail card sample line type; S3: connecting a head alignment point and a tail alignment point to generate a connecting line segment, and simultaneously extending the head card sample rod and the tail card sample rod and intersecting at a point O; S4: equally dividing the connecting line segments according to the number of the residual card sample line types between the head card sample line type and the tail card sample line type, and creating equal division points with equal number; and S5: creating a sample card rod corresponding to the residual card sample line type. The non-parallel line type card sample quasi-line point solving method provides a method for calculating the card sample quasi-line points specially aiming at the non-parallel lines, so that the calculation process of the non-parallel lines is more reasonable.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a method for obtaining a non-parallel-line card-sample alignment point. Background technique [0002] There are many curved plates in the ship. In order to ensure the processing accuracy of these curved plates, the existing technology usually adopts the method of clamping and shaping. One curved plate needs to design multiple clamping samples. The card-like line type that matches the curvature of the corresponding part of the plate. By arranging these card samples on the corresponding rib line during use, the card-like line types on these card samples can be pieced together into the approximate shape of the curved plate. Contour, so as to realize the positioning of the bending accuracy of the plate. At present, the processing of each card needs to refer to the designed card pattern. An important step in the card pattern is to determine the alignment point. [0003] At presen...
