Description
Technical field
The present invention relates to double-curve cooling column manufacturing technology fields, and in particular to a kind of double using Visual LISP progress
The method that curve cooling tower cylinder wall form merogenesis calculates.
Background technology
AutoCAD is starting to 2019 versions of AutoCAD so far from 1982, is widely used in two-dimensional graphics, draws in detail,
Now have become drawing tool popular in the world.It is a more mature drawing platform, it is in addition to powerful
Outside editting function, also have the function of that the exchanging visit of figure number, figure are several, number is figure, approach vector expression, though through multipole amplification or
It reduces, remains to keep precision constant.
AutoLISP specially designs for secondary development AutoCAD, originate from list processing language, be list processing language and
The product that AutoCAD is organically combined, is embedded in AutoCAD, many functions is increased for AutoCAD, has AutoCAD strong
The characteristics of big graphic editing function.Start to be integrated with Visual list processing languages in AutoCAD 2000, provide more open
Secondary development environment.It is completely compatible with AutoLISP, and the institute for providing AutoLISP is functional, is able to access that AutoCAD
More document environments, be very suitable for the application and calculating of figure.It can order the drawing of AutoLISP programs and AutoCAD
Order pellucidly combines, and design and drawing is made to combine together completely, and various engineerings point can be carried out using AutoLISP language
The figure that analysis calculates, automatic drafting is complicated.
Cooling tower is an important water conservancy project structure in thermal power plant.Current most of thermal power plants all use double
Curved cooling stack.The shape of this cooling tower is by inside and outside barrel surface curve around centre of cooling column axis rotary
At shell, longitudinal section center line (busbar) is exactly hyperbola.Barrel template construction is that alternating is gradually circulated up by bottom
It carries out, until tower top, general tower top final section criteria of right and wrong section.
The country is generally constructed using adhesion type tripod setting-up formwork method at present.Barrel is typically just pressed in design drawing
Face merogenesis gives the geometric dimensions such as corresponding absolute altitude, radius and wall thickness in shell, without providing scaffold cradle construction institute
What is needed is carried out the geometric dimension of merogenesis in stack shell surface generatrix direction by form height.Such as corresponding absolute altitude in each layer template top,
To drawing between inner and outer template top radius, wall thickness, template block number, internal surface area, every board concrete side's amount and inside and outside scaffold cradle
Concrete jacket length of tube etc. at bolt, and these data are essential in construction, construction survey and quality examination are checked and accepted
These data must be used.So the merogenesis that carry out stack shell template according to design drawing before construction calculates, and it is depicted as applying
Work technical indication chart, as manufacture bases.Stack shell merogenesis calculates usually amplification sample actual measurement, calculus of finite differences calculating, curve in the past
The methods of formula calculating.
1 amplification sample measurement method：
Before CAD is not popularized or 1:1 (or 1:2~1:10) ground setting-out on the scene.Amplify sample needed for place compared with
Greatly, time-consuming.It is difficult measured data after setting-out that ground on the scene, which identifies a point without radius and the line without width, because measuring
Itself there is error always, it should say that the construction data precision that this method obtains is not high, large scale error is with regard to bigger.
2 calculus of finite differences merogenesis calculate：
Barrel merogenesis construction geometric dimension, which is calculated, using calculus of finite differences saves place, Er Qiefang than putting large sample method time and labour saving
Method is simple, as long as can be calculated with elementary mathematics knowledge.But in calculating process there are two assume, it is assumed that regard barrel as
By the broken line of design merogenesis height change, it is assumed that barrel is using every piece of form height as the broken line of modulus, so inserting after merogenesis
Enter and will appear certain radius error and absolute altitude error in calculating process.
3 curve equation calculating methods：
With reference to《The construction of armored concrete hyperbola cooling tower》,《Concise unique construction design and construction data is integrated》It calculates
Formula, the merogenesis that cylinder wall is carried out using hyperbola formula are calculated, are calculated surface curve in shell, find out data is barrel
Face absolute altitude and radius in shell, and what is desired is that interior (or outer) side template radius and absolute altitude suitable for reading in practice of construction.So
It also to convert again, could really obtain the data for meeting construction requirement.This method accuracy is high, and accumulated error is smaller,
Calculate very complicated in the case of not programming, and result data is not intuitive, and having zero defect, also inconvenient verification checks.
Can the curve and wall thickness accuracy of Hyperbolic cooling tower cylinder directly affect the total quality of cooling tower, and ensure
The precision of cylinder depends on used template and its location control technology again.Data used in Cooling Tower Wall Construction precisely exist
Data on surface of shell curve.Since upper ring beam, lower ring near zone shell are Varying-thickness, even if face is available in shell
Simple function expression formula expresses curve equation, surface of shell curve because being no longer hyperbola after Varying-thickness, ring beam region just not
It may be expressed again with simple function expression, it is necessary to piecewise fitting function is used, quasi- with the given merogenesis data of design
During closing function, precision necessarily reduces.Designing institute will not generally provide the analytical function of barrel curve to unit in charge of construction, lead to
The drawing that reason Kuang Xia designing units connect DWG formats will not provide, can with mathematical software matlab, Mathematica etc.
Inverting is carried out to be fitted to calculate, but result and AutoCAD ratios be not intuitive.Utilize AutoCAD platforms and embedded Visual
List processing language, programming realize that merogenesis calculates, can more perfectly solve the problems, such as this.
