Common pressure vessel design software
As the pressure vessel is more and more widely used in various industries, the role is becoming more and more prominent, in order to meet the requirements of the manufacture and use of pressure vessels, the requirements for the design are also increasingly high. As the design of pressure vessels, not only to master the relevant professional knowledge, according to the relevant standards and requirements for structural design and strength, stiffness and other aspects of the calculation, but also need to optimize the pressure vessel force, structural dimensions, materials, etc., to meet the rationality and economy of pressure vessel design.
The calculation of the strength of the pressure vessel is an extremely tedious task, which needs to be calculated, judged and standardized on the basis of the relevant standards for the stress of the pressure vessel, and finally form the archived information of the pressure vessel. This often takes up a lot of manpower, material resources and time. Therefore . Development and application of some design software, to improve the efficiency and design quality of pressure vessel design, the development of better performance of the pressure vessel is a very meaningful work.
Over the past decades, many companies and institutions at home and abroad (domestic: National Chemical Equipment Design Technology Center Station, Gansu Lanke Petrochemical High-tech Equipment Co. Overseas: ASKA of Germany, PAFEC of UK, SYSTUS of France, ABAQUS, ADINA, ANSYS, BERSAFE, BOSOR, COSMOS, ELAS, MARC, CODEWARE, Bentley and STARDYNE of USA) have carried out the development of pressure vessel software.
Through the efforts of scholars and experts, many excellent design software have been developed, such as SW6-2011 process equipment strength calculation software package, LANSYS pressure vessel strength design software, TANK tank design software, CAESARII pipe stress analysis software, Pvelite&.CodeCalc, COMPRESS, and AutoPipeVessel (MicoroProtol), VVD pressure vessel overall and parts analysis and design software, MT-EXCH shell and tube heat exchanger analysis and design software, NozzlePro pipe nozzle finite element analysis software, FE/PIPE finite element method pressure vessel and pipe stress analysis software and FEPG, JlGFFX, HAJIF, ANSYS, ABAQUS, ADINA, DYNA3D, NASTRAN, ASKA, ALGOR, BEASY, AFEMS, PAFEC, SYSTUS and other finite element analysis and design software.

LANSYS Pressure Vessel Strength Design Software
LANSYS is a set of design software developed by Lansen Petrochemical Technology Co., Ltd. It is compiled according to GB/T150.1-150.4, GB/T151, GB/T16749, GB/T12337, NB/T47041, NB/T47042, HG/T20569 and related basic standards, and under the principle of respecting the original standards and industry customs A reasonable classification has been made, and more than 80 kinds of parts items (calculation items) are grouped into five categories: shell and head, flat cover and flange, heat exchanger parts, non-circular cross-section vessels, and cylinder ends, and equipment categories include heat exchangers, horizontal vessels, upright vessels, spherical storage tanks, agitators, and other major categories.
LANSYS operates with the user in mind. The user selects the required equipment and can add parts, moreover, the user can combine parts to build his own equipment, and even the part names can be named by the user.
LANSYS’ powerful just-in-time calculations, combined with data entry, graphical prompts, and same-page integration of calculation results, allow users to see what they see, even important intermediate data, in a timely, intuitive and efficient manner.
The workbook design with page tabs makes switching between calculation items accurate and fast, just like looking through a design book, and the page tab icon will change from red to green after the calculation item is passed.
The default value setting of input data and the function of applying data of standard components (e.g. flanges, sections) not only reduce the user’s work intensity, but also provide the user with reference data.
LANSYS automatically generates design calculations in a standardized format, adding covers, tables of contents and graphical formulas and even tables for easy archiving by the user.
LANSYS has powerful project file organization and management functions, such as multi-document function, copy and paste function, sort and delete function, etc. The project file includes calculation contents, calculation modes, input and output data and reports, all of which are managed by LANSYS itself without the support of third-party software, and the file is very small, usually only about 10 KB.
The four data of design pressure, design temperature, nominal diameter and pressure test type of each calculation item in the equipment project are interrelated, and once modified, all the relevant calculation items dynamically generate calculation results, and automatically find out the minimum value of test pressure in the calculation item as the equipment test pressure.
The detailed LANSYS help quotes the original drawings of the standard as far as possible, so that the user can get accurate help and be familiar with the standard itself at the same time.
Material entry and management functions allow users to easily use materials other than the standard.
LANSYS successfully passed the test evaluation of the Computer Application Sub-Technical Committee of the National Pressure Vessel Standardization Technical Committee in July 1999. The evaluation concluded that LANSYS adopts advanced software programming technology and has its own characteristics in terms of friendliness of software interface, ease of operation, establishment of external material database and management of standard parts database and calculation documents, etc., which is advanced among similar software in China.

ANSYS Analysis and Design Software
ANSYS software is the first large-scale analysis and design software that has passed the ISO9001 quality certification, and is the standard analysis software certified by the American Society of Mechanical Engineers (ASME), the U.S. Nuclear Safety Administration (NQA) and nearly 20 professional technical associations.
It is the first software in China that has passed the certification of the Technical Committee for Pressure Vessel Standardization and has been promoted and used by 17 ministries of the State Council. Now there are many pressure vessel design units using ANSYS finite element analysis software for the design of pressure vessels.
ANSYS software is a large general finite element analysis software integrating structure, fluid, electromagnetic field, sound field and coupling field analysis. It is developed by ANSYS, one of the world’s largest FEA software companies, and can interface with most CAD software to realize the common grass and exchange of data, such as Pro/Engineer, UG, SolidWorks, NASTRAN, Alogor, CATTAJ-DEAS, AutoCAD, etc. It is one of the advanced CAE tools in modern product design. ANSYS finite element analysis software can perform analysis and calculation of the whole or parts of the equipment.
ANSYS software consists of three main parts: pre-processing module, analysis and calculation module and post-processing module.
The pre-processing module provides a powerful solid modeling and mesh partitioning tool that allows users to easily construct finite element models.
The analysis and calculation module includes structural analysis (linear analysis, nonlinear analysis and highly nonlinear analysis), fluid dynamics analysis, electromagnetic field analysis, acoustic field analysis, piezoelectric analysis and coupling analysis of multi-physical fields, which can simulate the interaction of various physical media and have the ability of sensitivity analysis and optimization analysis.
The post-processing module can display the calculation results as color contour display, gradient display, vector display, particle flow trace display, stereo slice display, transparent and semi-transparent display (you can see the inside of the structure) and other graphics, and can also display or output the calculation results in the form of graphs and curves.
The software provides more than 100 cell types to simulate various structures and materials of engineering towels. The software is available in many different versions and can run on a wide range of computer equipment from personal machines to mainframes. It can be used not only for stress analysis and fatigue analysis of pressure vessel design, but also for optimization of pressure vessel design, which occupies an extremely important position among various pressure vessel design software.
ABAQUS analysis and design software
ABAQUS is a powerful finite element software for engineering simulation, and its problem solving range from relatively simple linear analysis to many complex nonlinear problems. It also has a library of material models of various types to simulate the properties of typical engineering materials, including metals, rubber, polymers, composites, reinforced concrete, compressible superelastic foams, and geological materials such as soil and rock. As a general-purpose simulation tool, ABAQUS can solve a large number of structural (stress/displacement) problems in addition to many other engineering fields, such as heat transfer, mass diffusion, thermoelectric coupling analysis, acoustic analysis, geotechnical analysis (fluid penetration/stress coupling analysis) and piezoelectric dielectric analysis.
ABAQUS provides users with a wide range of capabilities and is very easy to use. A large number of complex problems can be easily simulated by different combinations of option blocks. For example, complex multi-component problems are simulated by combining option blocks that define the geometry of each component with the corresponding material properties option block. In most simulations, even for highly nonlinear problems, the user only needs to provide some engineering data, such as the geometry of the structure, material properties, boundary conditions, and loading conditions. In a nonlinear analysis, ABAQUS can automatically select the appropriate load increments and convergence limits. It is not only possible to select the appropriate parameters, but also to continuously adjust them to ensure that the exact solution is efficiently obtained during the analysis. The user is able to control the numerical calculation results by defining the parameters exactly.
ABAQUS has two main solver modules-ABAQUS/Standard and ABAQUS/Explicit. ABAQUS also includes a graphical user interface that fully supports the solver, the human-computer interaction pre and post-processing module-ABAQUS/CAE. ABAQUS also provides specialized modules to solve specific problems.
ABAQUS is widely regarded as the most powerful finite element software for analyzing complex structural mechanics systems of solids, especially for navigating very large and complex problems and for simulating highly nonlinear problems.
The system-level analysis feature of ABAQUS is unique compared to other analysis software. ABAQUS is widely used in industry and research in many countries due to its excellent analytical capabilities and reliability in simulating complex systems.
