Description
Technical field
The present invention relates to rubber Analysis of Parameters.
Background technology
When developing rubber with enhancement layer, dissecting and analyzing sample structure and technological parameter is absolutely necessary.So just can better digest and use for reference the design concept of sample, just can design the higher goods of performance.Such as to the development of the nonstandard high-pressure rubber pipe of heavy caliber, in order to provide research and reference basis for design, unknown parameter sample hose is carried out hand-dissection and measurement layer by layer.Because body cross section diameter is comparatively large, internal diameter is Φ 500 ㎜, external diameter Φ 670 ㎜, and internal layer, middle level, skin have 4 layers of wire rope composite strengthening layer, and wire rope density is very high, and every layer has hundreds of root, causes great difficulty to statistics steel wire quantity.Not only to determine xsect every layer steel wire number, also will determine the run-length data of every layer, longitudinal cross-section steel wire.Its difficulty has 3 points: one, steel wire quantity is large, and complicate statistics is wasted time and energy, and precision is not high, is easy to debugging; Two, block owing to causing fusing glue-line to cover in anatomic course, cannot correctly add up at steel wire position out of stock; Three, due in anatomic course steel wire and steel wire mix, be unified into a slice, be difficult to distinguish the number of share of stock of wire rope, bring very large difficulty to statistics.
Summary of the invention
The object of the invention is to solve the difficult problem accurately checking and examining rubber complexity, various enhancement layer technological parameter.
For achieving the above object, its technical scheme designs the assay method with enhancement layer rubber unknown parameter, and its operation steps is as follows:
A. sample preparation: will have enhancement layer rubber vertically, radial or longitudinal direction, the laterally obtained section of cutting respectively;
B. respectively rubber section plane is scanned: select flat bed scanner to scan the axial section of product and radial section;
C. scan image input computer;
D. scan document image is imported in AutoCAD software: AutoCAD software is opened, " raster image reference " instrument is clicked in " insertion " toolbar, eject dialog box, click " browsing " button, select the picture file of just scanning, in " convergent-divergent " ratio hurdle, input ratio is 1, enters workspace after clicking " determination ", click in workspace, scanning document just imports in AutoCAD software;
E. draw in AutoCAD software and define statistical model: drawing an obvious dot of color with AutoCAD software, the diameter of round dot is suitable with the cross-sectional sizes of enhancement layer wire rope or fiber rope, then dot is defined as data model;
F. statistical model carries out position with the enhancement layer in scan image and Population number dynamic imitation overlaps: automatically copied by the steel wire quantity in scan image and position by dot data model, finely tune after copying again, dot and wire rope are simulated completely and overlaps;
G. programming count model quantity: the dot frame choosing that will add up, automatically will show the quantity of dot quantity namely this enhancement layer wire rope or fiber rope in " characteristic instrument " hurdle of AutoCAD software;
H. the surveying and calculating of various unknown parameter:
(1) surveying and calculating of winding pipe product parameter: enhancement layer wire rope radical, steel wire radical/stock, the number of plies, sebific duct diameter, winding stroke, winding angle, inner glue layer thickness, mesoglea thickness;
(2) surveying and calculating of woven tube product parameter: enhancement layer steel wire radical, the number of plies, sebific duct internal diameter, external diameter, braided pitch, angle of weave, inner glue layer thickness, mesoglea thickness, steel wire radical/stock;
(3) surveying and calculating of machine alternate product parameter: enhancement layer wire rope radical, the number of plies, wirerope diameter, wire rope arrangement size;
(4) surveying and calculating of tire product parameter: enhancement layer steel wire radical, the number of plies, steel wire and fiber rope diameter, steel wire and fiber rope arrangement size.
The present invention is that the method for the specific function programming count sample enhancement layer process data utilizing computer software is simple, practical, accurate, decreases and manually successively cuts open stripping operation, saves manpower and labour intensity.Not only can be applied in the parametric statistics of rubber, also can apply in the parameter mapping statistics of other products, range of application is very wide, is worthy to be popularized.
Embodiment
embodiment:for internal diameter Φ 500 ㎜ heavy-caliber high-pressure rubber hose, describe concrete operation method of the present invention and step in detail:
A. sample preparation: by have the large-bore hose of wire rope enhancement layer vertically, radial direction cuts obtained section respectively;
B. respectively to the large-bore hose section plane scanning for measuring: select flat bed scanner to scan the axial section of product and radial section;
C. scan image input computer: the enhancement layer scan image input computer that large-bore hose is dissected;
D. enhancement layer scan document image is imported in AutoCAD software: AutoCAD software is opened, " raster image reference " instrument is clicked in " insertion " toolbar, eject dialog box, click " browsing " button, select the picture file of just scanning, in " convergent-divergent " ratio hurdle, input ratio is 1, enters workspace after clicking " determination ", click in workspace, scanning document just imports in AutoCAD software;
E. draw in AutoCAD software and define statistical model: drawing an obvious dot of color with AutoCAD software, the diameter of round dot is suitable with the cross-sectional sizes of enhancement layer wire rope, then dot is defined as data model;
F. statistical model carries out position with the enhancement layer in scan image and Population number dynamic imitation overlaps: automatically copied by the steel wire quantity in scan image and position by dot data model, finely tune again after copying, dot and wire rope are simulated completely overlap, can also revise and error correction according to constant spacing in the place of steel wire defect;
G. programming count model quantity: the dot frame choosing that will add up, automatically will show the quantity of dot quantity namely this enhancement layer wire rope in " characteristic instrument " hurdle of AutoCAD software;
