Abstract
A stress calculation and safety assessment method for a spherical tank on differential settlement ground is provided. A plurality of steps in an ANSYS analysis process are programmed to be a parametric command flow through an ANSYS secondary development language APDL (ANSYS Parameter Design Language), programming is performed in VB6.0 (Visual Basic 6.0) according to a parametric APDL code of a model, followed by background packaging, the above process can be visualized by means of a user interface program of human-computer interaction of VB (Visual Basic), a user can only input a calculating parameter on a system interface, background ANSYS software can be invoked for analysis through a VB invoking interface program and postprocessing can be performed through a VB postprocessing program, and a calculation result can be fed back to the user. According to the stress calculation and safety assessment method for a spherical tank on differential settlement ground provided by the invention, a complex ANSYS analysis process is visualized, stress calculation and simulation can be performed on a spherical tank on non-standard settlement ground, and the operation is simple.
Description
Technical field
The present invention relates to a kind of Stress calculation and Safety Assessment Methods of foundation uneven settlement spherical tank, be applicable to the various industries such as oil, chemical industry, the energy and use spherical storage tank.
Background technology
Spherical tank is one of conventional storage facilities, it is widely used in various industry and the gas stations such as oil, chemical industry, the energy, the spherical tank now run is more than 10000, the spherical tank that the spherical tank of the in-service operation of current China, the especially eighties build, has much entered the Frequent Accidents stage, often there is foundation uneven settlement, foundation uneven settlement makes load skewness on each pillar, and produces extra-stress on pillar, and the larger pillar of part carrying may take the lead in destroying.This has buried hidden danger to the safety of spherical tank, has had a strong impact on the safe operation of spherical tank, has made the dangerous matter sources that spherical tank becomes potential, and causes very large threat to environment, life and national wealth.
For the extra-stress that foundation uneven settlement produces, act.std GB12337 " Steel made Ball storage Tank " does not have explanation in this respect, and study general in this respect all adopts ansys software to calculate at present, but this software operation is complicated, not easily grasps.The Stress calculation of foundation uneven settlement spherical tank of the present invention and Safety Assessment Methods, can the Stress calculation of optimized integration non-uniform settling spherical tank and man-rate easily.
Summary of the invention
The object of this invention is to provide a kind of simple to operate, be easy to the Stress calculation of foundation uneven settlement spherical tank grasped and Safety Assessment Methods.
The Stress calculation of a kind of foundation uneven settlement spherical tank provided by the invention and Safety Assessment Methods, by ANSYS secondary development language APDL, multiple steps of ANSYS analytic process are compiled into parametrization command stream, then the parametrization APDL code according to model in VB 6.0 is programmed, and carry out backstage encapsulation, utilize the user interface program of the man-machine interaction of VB by above process visualization, user only need input calculating parameter at system interface, namely the ANSYS software by VB calling interface routine call backstage carries out analyzing and carrying out aftertreatment by VB post processor, and result of calculation is returned to user.
In above-mentioned, multiple step comprises modeling, imposed load, applying boundary condition, solves calculating and interpretation of result.
In above-mentioned, the main completion system of user interface program and user's is mutual, comprises calculating parameter input and writes forward and backward processing command stream two parts of APDL; When all parameters input are complete, user clicks the computed push-buttom wanting to realize, and system will generate under APDL calculation command stream also exists the catalogue of specifying automatically with document format.
In above-mentioned, VB calling interface program play a part within the system to accept user interface input, create process transfer ANSYS module, the APDL command stream file of generation is submitted to ANSYS program carry out computing, user again clicks and wants the computed push-buttom realized can perform corresponding calculating.
In above-mentioned, VB post processor is for extracting the result data of calculating, and the working procedure of ANSYS, is connected on this control for medium with the control in VB by system, thus can call ANSYS under VB interface, achieves the connection of ANSYS and VB; Like this, just can carry out automatic calculation by running the ANSYS macroprogram developed, and acquired results is presented in VB interface, thus realize the transmission of data between ANSYS and VB, under VB interface, check the result of calculation of ANSYS.
Advantage of the present invention: the ANSYS analytic process of complexity to be carried out visual by native system, parametrization APDL code according to model in VB is programmed, backstage encapsulation has been carried out to ANSYS parametrization command stream, user only need input calculating parameter at system interface, the ANSYS software that can call backstage carries out analyzing and aftertreatment, and result of calculation is returned to user.Native system dynamically can generate the command stream text of APDL, and utilize the Shell function of VB to realize the backstage Linked Invoke of VB to ANSYS software, ANSYS background process graphic result out again by VB interface display out, the spherical tank that this software can exceed standard to foundation settlement carries out Stress calculation and simulation, and Dynamic System is simple, only need input calculating parameter at system interface, the ANSYS software that can call backstage carries out analyzing and aftertreatment, is applicable to very much the librarian use be not familiar with ANSYS software.
Accompanying drawing explanation
Fig. 1 is program development process flow diagram of the present invention.
