Abstract
The present invention is one universal intelligent software suitable for especially the precise analysis of large complicated beam. For statically determinate beam or super statically determinate beam comprising fixing end, fixed and mobile hinge bearer, elastic bearer and sink bearer combination to bear concentrated force, concentrated force couple or homogeneously distributed force, when various kinds of mechanical performance information, including bearing information, load information, section information and material, are input, the precise solutions of bearer counterforce, maximum internal force and its position, maximum deformation and its position and maximum stress and its position may be obtained fast and relevant curves may be drawn if necessary. The relevant information may be also provided, the structural model may be created, and the input information may be altered after returning to the input interface.
Description
Affiliated technical field
The present invention relates to a kind of beam be carried out the intelligence software of Accurate Analysis, be particularly useful for building, field multi-load multi-support such as bridge, machinery and have that the rank tee section is large-scale, complex beam fast and Accurate Analysis.
Background technology
At present, be based upon the classical mechanics on the continuous function basis, the complex beam that comprises many discontinuous factors such as intensive quantity (as concentrated force, concentrated couple) and variable cross section accurately (or parsing) analyzed still not to have unify and effective method, no matter be to the finding the solution or the analysis of internal force and distortion is all carried out in the fragmented mode of a kind of segmentation of constraining force, thereby seem loaded down with trivial details unusually.And the numerical approximation method desire acquisition enough accuracy amount of calculation that is based upon on finite difference or the finite element basis is huge, in the optimal design of beam, in fact be difficult to use, thereby limited the designing quality of beam to a certain extent owing to will carry out repeatedly iterative computation.
Summary of the invention
For overcoming the shortcoming of existing beam computational analysis method, the invention provides a kind of intelligence software, to by stiff end, rocker bar bearing, elastic support, have that the bearing combination in any of depression forms, bear any concentrated force, concentrated couple, even distributed force and have the static determinacy or the statically indeterminate beam of any stairstepping, as long as method is in accordance with regulations filled in for information about, the precise information of constraint reaction, internal force and distortion can be obtained rapidly, and interior force curve, deformation curve, stress curve and iso-intensity curve can be drawn as required.
The technical solution adopted for the present invention to solve the technical problems is: state coordinate system, load positive dirction and other application notice that is adopted behind the running software on the interface that at first occurs; Continue inputting interface to occur after the operation, key in the mechanical property information of supporting information, load information, geometry information and material of beam by the dimension of prompting after, program will be according to the automatic generating structure model of input information, the user checks in view of the above, if the wrong inputting interface that can return of input is made amendment to input information; Operation back program is calculated and output digital computation result once more, and the user can select as required to quit a program or draw all kinds of analytic curves.
The language that this software adopts is Visual Basic6.0, the principles of science of institute's foundation is: utilize singular function and infinitesimal analysis thereof and Laplace transform character, derive beam internal force, section modulus, the uniform expression of distortion, stress and equal strength cross section property, and utilize the boundary condition of supporting place to determine constraint reaction, just can utilize the above various relative curve that calculates or draw then.
The invention has the beneficial effects as follows: melt static analysis, internal force analysis, deformation analysis and stress intensity and analyze in one, can be easily and quickly to what form by all kinds of bearing combination in any, bear and concentrate arbitrarily or uniformly distributed load and static determinacy or statically indeterminate beam with any rank shape carry out Accurate Analysis.This software has general applicability to all kinds of beams, friendly interface is easy to use, scale and calculated amount are little, not only can reduce designer's labour intensity, can also when beam is implemented optimal design, set up internal force constraint, deformation constrain or stress intensity constraint easily, improve the designing quality of beam effectively.
Embodiment
The statement interface at first appears after the program run, in order to coordinate system, load positive dirction and other application notice that illustrates that this software adopts, program continues operation after selecting section form, inputting interface appears in screen, keying in program after the mechanical property information of supporting information, load information, geometry information and material of beam to be analyzed will generate automatically and the structural model of output beam according to input information by the dimension of prompting, the user checks in view of the above, if the wrong inputting interface that can return of input is made amendment to input information, otherwise continue working procedure.Software moves back calculating and output digital computation result once more, and the user can select as required to quit a program or draw various analytic curves; After finishing, curve plotting can quit a program.
