ANSYS 6206 Bearing Finite Element Analysis Process Command Flow

Solution: To determine the bearing force distribution, first divide the bearing surface into two halves, apply the bearing load in the stressed half, and specifically command the load to change the position of the broken coordinates in the load, add the load boundary in the ug, and then import ANSYS.

ANSYS software is a large-scale general finite element analysis (FEA) software developed by ANSYS in the United States, which is the fastest growing computer-aided engineering (CAE) software in the world, which can interface with most computer-aided design (CAD) software to achieve data sharing and exchange, such as Creo, Nastran, Alogor, I Deas, AutoCAD, etc. It is a large-scale general finite element analysis software that integrates structure, fluid, electric field, magnetic field and acoustic field analysis. It has a wide range of applications in nuclear industry, railway, petrochemical, aerospace, machinery manufacturing, energy, automobile transportation, national defense and military industry, electronics, civil engineering, shipbuilding, biomedicine, light industry, geology and mining, water conservancy, household appliances and other fields.

Powerful, simple and convenient, ANSYS has become the most popular finite element analysis software in the world, and has been ranked first in FEA evaluations over the years. At present, more than 100 science and engineering colleges in China use ANSYS software for finite element analysis or as standard teaching software.

First, divide the surface of the bearing into two halves, and apply the bearing load to the stressed half, and specifically command the load.

APDL stands for Ansys Parametric Design Language, which is a parametric design language. It can be used to complete some versatile tasks, and can also be used to build models based on it, which is not only the basis for the implementation of classic ANSYS features such as optimized design and adaptive meshing, but also provides convenience for daily analysis. The standard process for finite element analysis includes:

Define the model and its loads, solve and interpret the results, and if the solution results show that it is necessary to modify the design, then you must change the geometry or loads of the model and repeat the above steps. Especially when the model is more complex or has a lot of modifications, this process can be expensive and time-consuming. APDL provides the user with the ability to automate the above loops by creating intelligent analysis, i.e., the input of the program can be set to make decisions based on specified functions, variables, and selected analysis criteria.

It allows for complex data entry, giving the user control over any design or analysis attributes, such as geometric dimensions, materials, boundary conditions, and mesh density, extending capabilities beyond the scope of traditional finite element analysis and augmenting more advanced operations including sensitivity studies, parametric modeling of parts, design modifications, and design optimization. It provides great convenience for users to control the process of any complex calculation. It essentially consists of a programming language similar to Fortran77 and more than 1,000 Ansys commands.

Like other programming languages, the programming language section has parameters, array expressions, functions, flow control (loops and branches), repeated execution of commands, abbreviations, macros, and user programs. Standard ANSYS program runs are driven by more than 1,000 commands that can be written into a program written in a programming language, and the parameters of the commands can be assigned to a definite value, or they can be assigned as a result of an expression or as a parameter. Functionally, ANSYS commands correspond to commands such as defining geometry, meshing elements, defining materials, adding loads and boundary conditions, controlling and executing solution and post-processing results during the ANSYS analysis.

Users can use the programming language to organize ANSYS commands and write parametric user programs, so as to realize the whole process of finite element analysis, that is, the establishment of parametric CAD models, parametric meshing and control, parametric material definitions, parametric load and boundary condition definitions, parametric analysis control and solving, and parametric post-processing.

ANSYS accelerates the flow of running commands.

There is a book called "Ansys APDL Parametric Finite Element Analysis Techniques and Their Application Examples", and I recommend you to check it out.

If your English is okay, you can directly read the help literature that comes with ANSYS installation, which is very detailed. The Chinese version of the textbook is basically a translation of the help literature. There are many example problems in it, both the GUI operation process and the APDL command flow operation.

The best way for novices to learn is to find a few example problems and do them a few more times, and after understanding the process, you will have some ideas.

In addition, ANSYS has many modules, and the textbooks you choose should be based on your application field.
