A Calculation Method of Non-parallel Line-type Card-sample Alignment Points

Abstract

The invention relates to a method for obtaining a non-parallel line type card-like directrix point. It includes the following steps: S1: make the first vertical line through the first card sample line type, and make the tail vertical line through the end card sample line type; S2: intercept the set length on the first vertical line to create the first card corresponding to the first card sample line type. Clip-like bar, starting from the intersection point of the tail-card-like line type and the tail-perpendicular line, intercepting the set length on the tail-vertical line to create a tail-card-like rod corresponding to the tail-card-like line type; S3: connecting the first alignment point and the tail Alignment points and generate connecting line segments, while extending the first card sample bar and the tail card sample bar and intersecting at point O; S4: According to the number of remaining card sample line types between the first card sample line type and the tail card sample line type, the Divide the connected line segments equally, and create equal number of equally divided points; S5: Create the card-like bars corresponding to the remaining card-like line types. The method for obtaining the directrix point of the present invention provides a method for obtaining the card-like directrix point specially for the non-parallel line type, which makes the process of obtaining the non-parallel line type 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...
