Finite Element Analysis software, also known as FEA software, is a common tool for every mechanical engineer today.<\/p>\n
In the current market, there are many challenges to face in order to keep competitive. High profitability needs high quality products. Thus, product development engineers, QA engineers, reliability engineers, design engineers, etc. have to do their utmost to achieve that quality.<\/p>\n
Some of the challenges include performing tests to make sure the parts and materials of their products behave as expected. That includes reactions to different situations including forces, vibrations and heat.<\/p>\n
In the past, these tests were performed by creating a prototype of the product and performing the tests on it. However, creating prototypes and testing on them usually takes time and results in higher costs.<\/p>\n
Using Finite Element Analysis, therefore, aligns very well with lean manufacturing methods<\/a> in order to maximise productivity and minimise waste.<\/p>\n Finite Element Analysis (FEA) is a type of computerised analysis method. It is used to study simulated physical phenomena which is based on the Finite Element Method (FEM)<\/a>. FEM is a numerical method that uses mathematical models to solve complex structural engineering problems represented by differential equations.<\/p>\n Engineers use Finite Element Analysis in the design process. Instead of making prototypes for real-life experiments, they turn to Finite Element Analysis software.<\/p>\n Applying it during the design phase helps to optimise machinery parts to make better products and deliver them faster.<\/p>\n There are different stages in the design process. One of them is testing out solutions<\/a> to see if they meet the requirements and expected working behaviour.<\/p>\n First, the problem is defined. Market research is conducted in order to identify and specify the requirements. Then brainstorming and evaluation of different possibilities takes place. This includes modelling different parts and even whole assemblies by means of CAD software for better visualisation.<\/p>\n Fortunately, current CAD software<\/a> usually comes in the form of a package that includes other modules beyond modelling. Many of them already include FEA capabilities. Of those, many even work with fluids which is known as Computational Fluid Dynamics or CFD<\/a>.<\/p>\n Therefore, the models made in the previous stages of the design process can be used to test the possible solution. If necessary, redesigning the parts based on data and test results takes place.<\/p>\n Of course, it is also possible to export the models to another simulation software if necessary. Specialised software gives more accurate results and has more functions. For example, such optimisation is necessary for large-batch production. Over-dimensioning results in unnecessary costs that accumulate with series production<\/a>.<\/p>\n Now, there are some aspects to consider when applying FEA in the design process:<\/p>\n You have to be sure to select the right analysis type to get the correct results.<\/p>\n Static Analysis<\/strong><\/p>\nWhat is Finite Element Analysis?<\/strong><\/h2>\n
