Non-parallel linear card sample quasi-line point solving method

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...
