Abstract
Disclosed is a stress calculation method for a foundation uneven settlement spherical tank. The method includes the steps that the multiple steps of the ANSYS analysis process are compiled to be a parameterized command stream through the secondary development language APDL of ANSYS, and for the spherical tank with foundation settling, the stress of the foundation settlement spherical tank is calculated by modifying the constraint condition in a model command stream file, wherein the multiple steps include modeling, load application, boundary condition application, calculation for solutions and result analysis. The stress of the foundation settlement spherical tank can be calculated and analyzed by modifying the related parameters or constraint condition in the command stream file, repeated modeling is avoided, workloads are reduced, and the analysis time is largely shortened.
Description
Technical field
The present invention relates to a kind of calculation method for stress of foundation uneven settlement spherical storage 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 that present labour is run is more than 10000, the spherical tank of the in-service operation of current China, especially the spherical tank built the eighties, much enter the Frequent Accidents stage, often occur foundation uneven settlement.Load skewness on each pillar after foundation uneven settlement, and extra-stress is produced on pillar, 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 spherical storage tank " there is not explanation in this respect, the spherical storage tank that the present invention is directed to the pillar supporting of basic uneven sedimentation sets up computation model, utilizes model to carry out Stress calculation to foundation settlement spherical storage tank.
Summary of the invention
The object of this invention is to provide a kind of spherical storage tank model establishing the foundation uneven settlement of pillar supporting, utilize model can carry out Stress calculation to foundation settlement spherical storage tank.
The calculation method for stress of foundation uneven settlement spherical storage tank provided by the invention, the method is, by ANSYS secondary development language APDL, multiple steps of ANSYS analytic process are compiled into parametrization command stream, basis be there is to the spherical tank of sedimentation, by the constraint condition in amendment model command stream file, realize the Stress calculation to foundation settlement spherical tank.
In above-mentioned, multiple step comprises modeling, imposed load, applying boundary condition, solves calculating and interpretation of result.
Model of the present invention can apply following several load: gravity, pressure, wind load, seismic (seismal; Following several different load cases combination can be calculated: deadweight operating mode, operation operating mode, hydraulic testing operating mode, earthquake and wind load composite condition.The foundation uneven settlement spherical tank computation model that the present invention sets up can realize following calculating: there are the spherical tank of different settling amounts, the loading under a certain operating mode and Stress calculation in the basis of each pillar of (1) spherical tank; (2) loading of foundation uneven settlement spherical tank under various combination operating mode and Stress calculation.
The advantage that the present invention has: utilize ansys software platform, by APDL language, parametric modeling is carried out to spherical tank, the foundation's settlement different according to in-service spherical tank or the needs of analysis, by the correlation parameter in amendment command stream file or constraint condition, the object of Stress calculation to foundation uneven settlement spherical tank and analysis can be realized, avoid repetition modeling, decrease labor workload, substantially reduce analysis time.
Embodiment
Embodiment:
The calculation method for stress of foundation uneven settlement spherical storage tank provided by the invention, the method is, by ANSYS secondary development language APDL, multiple steps of ANSYS analytic process are compiled into parametrization command stream, basis be there is to the spherical tank of sedimentation, by the constraint condition in amendment model command stream file, realize the Stress calculation to foundation settlement spherical tank.Multiple step comprises modeling, imposed load, applying boundary condition, solves calculating and interpretation of result.
In the present invention, ANSYS analytic process comprises: modeling, imposed load, applying boundary condition, solve several steps such as calculating, interpretation of result, by APDL language, each step process is compiled into parametrization command stream, all numerical value scalar parameters, array parameter and expression formula function in each process represent, according to different analysis needs, only need revise the correlation parameter in command stream file: for the spherical tank of different types and size, relevant parameters can be revised in the parametrization command stream file of modeling; Footing of a pillar is had to the spherical tank of different settling amount, only need revise boundary condition command stream in applying boundary condition command stream file; Some specific spherical tanks are carried out to the analysis under different operating mode, only need add different loading command stream in loading command stream file.
