This section provides overview, applications, and principles of structural analysis softwares. Also, please take a look at the list of 6 structural analysis software manufacturers and their company rankings.
Structural analysis software is a technique that uses simulation to analyze physical quantities that change when loads are applied to the object being analyzed.
By conducting structural analysis software before actually creating the structure you want to build, you can reduce the risk of failure. It is also possible to obtain data for large-scale equipment that cannot be tested.
Structural analysis software is performed by modeling the object to be analyzed and using a computer to calculate the movement and displacement of the object to be analyzed caused by the application of loads and vibrations.
Structural analysis softwares are primarily used in the design phase of industrial products and buildings. Since the time required to obtain analysis results depends on the performance of the computer, it is necessary to select the structural analysis softwares to be used, taking into consideration the specifications of the computer to be used and the computational load for structural analysis softwares.
Here are some examples of the use of structural analysis softwares.
This section describes the principles of structural analysis softwares.
The structural analysis softwares method consists of the following steps: drawing the analysis target, cutting the mesh, modeling, inputting physical quantities, analysis, and output. Each of these steps is explained as follows.
There are various types of structural analysis softwares. Typical examples include static analysis, which calculates the deformation and stress of an object, eigenvalue analysis, which calculates the natural frequencies of an object, and heat transfer analysis, which analyzes the transfer of heat.
Static analysis can be used to calculate static changes in an object by setting constraints, load conditions, temperature conditions, and so on. It is the most common type of analysis used in machine design.
Eigenvalue analysis calculates the eigenvalues of an object. Eigenvalues are simply the frequencies at which resonance occurs, so if the eigenvalue is high, it can be determined that resonance is unlikely to occur. Since vibration affects the functionality of precision equipment mounts, eigenvalue analysis is performed to determine the shape so that the eigenvalue is as high as possible.
Heat transfer analysis calculates the heat distribution of an object. For example, by calculating the temperature distribution of a heater plate, the temperature uniformity can be predicted, allowing optimal design without manufacturing parts.
Structural analysis softwares are generally performed on a computer using dedicated software, but there are several items to keep in mind in order to obtain analysis results that are close to actual conditions.
One is how to create a 3D model. By making the model exactly the same as the actual geometry, errors may occur in the mesh processing or the analysis may take too long, and the analysis results may not come out well. It is necessary to distinguish between parts of the model that should be created in detail and parts that should be omitted, depending on what is to be analyzed.
The other is the conditions of the analysis. There are a variety of conditions, and if these are not set properly, analysis results will be far from the actual values.
For example, the analysis results will differ greatly depending on whether the entire mounting surface or only the bolted portion is to be secured, whether the load is an average load or a concentrated load, and so on, for the bolted restraint condition.
Even if the analysis software is excellent, accurate analysis results may not be obtained if the model or condition settings are poor.
