Description

The method for designing of the multiple latitude of a kind of canonical angle interlocking machine fabric

Technical field

The present invention relates to the method for designing of a kind of angle interlocking machine fabric, belong to textile technology field.

Background technology

The three-dimensional woven structural composite material is because it has splendid interlaminar shear strength, fabulous shock resistance is damaging, designability is strong, a series of characteristics such as specific strength is high, specific modulus is large, lightweight, can satisfy the requirement in the fields such as Aero-Space, communications and transportation, auto industry, shipbuilding, become one of common new material of paying close attention to and studying of field of textiles and Material Field.Angle-interlock fabric is exactly a member in this class new material, it is than being easier to woven tabular stereo fabric on ordinary loom, by organizing design can reach structural stability, compressibility, intensity and the fabric thickness of expection, be widely used in plate reinforced composite at home and abroad.But in the design process of angle-interlock fabric structure chart and organization chart, always design structure chart by hand first, and then design organization chart according to its structure chart, especially when fabric thickness is thicker, if rely on manual the design, not only waste a large amount of time, and make mistakes easily, as number of plies n=10, one 10 layers of traditional-handwork method design run through angle interlock figure, as shown in Figure 1, because of the number of plies more, design work is not only time-consuming, and easily makes mistakes.

Summary of the invention

The technical issues that need to address of the present invention are: in the design process of canonical multiple dimension angle-interlock fabric structure and tissue, always design by hand first structure chart, and then design organization chart according to its structure chart, when fabric thickness is thicker, if dependence hand-designed, not only waste a large amount of time, and make mistakes easily.

The invention provides the method for designing of the multiple dimension of a kind of canonical angle interlocking machine fabric, may further comprise the steps:

1) structure chart design;

The number of plies n of A, described structure chart and warp thread period Rj, weft yarn period Rw, warp thread fly between several Sj, the maximum floating long number Fm of tissue following relation: Rj=n+1 is arranged, Rw=n * Rj, and Sj=n, Fm=2n-1 calculates Rj, Rw according to n;

B, the EXCEL page is adjusted to square grid structure;

C, make the X reference axis along the lower-left of grid to upper right diagonal, set Rj along X-axis, makes the Y-axis vertical with X-axis, along Y-axis setting n and picking sequentially, in grid, carry out successively the picking serial number;

D, the EXCEL page is changed into the picture form, described picture turns clockwise 45 °;

2) organization chart design;

A, the EXCEL page is adjusted to square grid structure;

B, sketch the contours of the organization chart zone at the EXCEL page;

C, in described grid structure, mark respectively through interlacing point, latitude interlacing point and datum mark.

Characteristics of the present invention are, utilize the existing grid structure of EXCEL, carry out the structure chart of the multiple dimension of canonical angle interlocking machine fabric, the design of organization chart, and the designer needn't oneself draw map grid.

Beneficial effect of the present invention is:

1) the present invention utilizes EXCEL itself to possess the characteristic of grid, participates in design, can design accurately, easily its structure chart and organization chart by shirtsleeve operation.

2) need not separately warp yarn to be carried out hand-designed, accuracy improves greatly, is difficult for makeing mistakes.

3) improved the design efficiency of the multiple dimension of canonical angle interlocking machine fabric.

The specific embodiment

The invention will be further described below in conjunction with specific embodiment.

So-called multiple latitude angle-interlock fabric, to be interwoven with overlapping interlocking shape by warp thread and parallel, its warp thread runs through whole fabric thickness and carries out angle interlocking shape with each layer weft yarn with certain inclination angle and interweaves, when the weft yarn fineness is identical, normally 45 ° at warp thread inclination angle, if all inweave a weft yarn and only inweave a weft yarn in the oblique prong of two warp thread formation during the interlocking of angle, then this angle interlock is called the multiple latitude of canonical angle interlock.The number of plies n of this structure and warp thread period Rj, weft yarn period Rw, warp thread fly that following relation is arranged between several Sj, the maximum floating long number Fm of tissue:

Rj=n+1；

Rw=n×Rj=n×(n+1)；

Sj=n；

Fm=2n-1。

In addition, the weft yarn of the multiple latitude angle-interlock fabric of canonical is arranged on thickness direction in turn, is the n layer every the n latitude, repeats once, forms the regular angle interlock that runs through.This type of fabric thickness uniformity, Weft layers can design according to the required thickness requirement of actual fabric.

During design structure diagram, as shown in Figure 2, at first the Excel form to be arranged to squared paper.Specific practice is: open the Excel program, a newly-built Excel form is adjusted whole worksheet col width or row is high, so that each cell is square tessellated on the EXCEL page, carries out following FOUR EASY STEPS again:

The first step is calculated the filling yarn radical, runs through angle interlocking organizational parameter Rj=n+1=11 by canonical, Rw=n * Rj=n * (n+1)=110.

Second step, the blank figure of 10 layers of canonical angle interlock figure of design is namely designing on the squared paper of finishing in Excel, along diagonal angle, the left and right sides line drawing reference axis of grid: X-axis, Y-axis, as reference coordinates.Arabic numerals among the figure on the X-axis reference axis represent a warp thread period: 11 warp thread, and Roman number represents Weft layers and picking order on the Y-axis coordinate: 10 layers of weft yarn; Numeral weft yarn in the grid and the picking serial number of this weft yarn.The picking serial number is that this numbering is carried out successively by layer according to need to the numbering each root weft yarn of weaving process, meets the urgent requirement of weft yarn, until complete whole weft yarns numberings, and the grid frame overstriking that contains the weft yarn numbering.

The 3rd step, to need in the form to select the graphics field of preserving, remove grid lines, figure is copied pasting in the drawing board again, save as the JPG format picture.

In the 4th step, practical design software is opened picture, and picture is turned clockwise 90 °, can obtain structure chart shown in Figure 3.

During design organization figure, shown in Fig. 4-8, be four layers of canonical angle interlock figure among Fig. 4, according to calculating:

Rj=n+1=5；

Rw=n×Rj=n×(n+1)=4×5=20；

Sj=n=4

Fm=2n-1=7。

Carry out again following three steps operation:

The first step according to calculating Rj, Rw numerical value, is sketched the contours of first the Weaving Cycle zone; As shown in Figure 5, in structure chart, find out the rule that interweaves of first warp thread, then according to the designing requirement of fabric tissue, the first grid begins to fill out successively from bottom to top and paints the first warp thread sink-float rule that interweaves from the lower left corner, carry out " * " sign through interlacing point, the latitude interlacing point is not filled out any symbol, so until complete all interlacing points of first warp thread.

Second step, as shown in Figure 6, choose and copy the first warp thread sink-float rule that interweaves, first lattice are datum mark through interlacing point take the lower left corner, be painted with stain, by the initial seat that flies several Sj=n=4 and find second warp thread, the first warp thread sink-float rule that interweaves pasted this, later on each root warp thread.

The 3rd step exceeded the Weaving Cycle area part with second warp thread and shears, and pasted this warp thread lower end area of absence, as shown in Figure 7, and later each root warp thread, until finish the organization chart design, as shown in Figure 8.

Simultaneously, also can use the same method and design respectively reed draft, drafting plan and pegging plan etc., consist of one group of complete looming draft.
