What Is Structural Analysis Software?
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.
Uses of Structural Analysis Softwares
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.
- Analysis of forces applied to materials and displacement of materials during press work
- Analysis of damage to an automobile during a collision
- Analysis of a building collapsing due to an earthquake
- Analysis of elastic impact of rubber materials
Principles 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.
- Drawing the Object To Be Measured
Draw the object to be analyzed using CAD or other software. Mainly, 3D CAD is used. If you are using a CAD software, it is recommended to check if the file format of the CAD software is compatible with the structural analysis softwares to be used. - Cutting the Mesh
The analysis object is decomposed into a grid called a mesh. The accuracy of this decomposition will affect the accuracy and speed of the calculation. - Modeling
Model the object to be analyzed. It is common to consider the boundary surfaces of each mesh as springs. - Enter Physical Quantities
Enter the Young's modulus, specific heat, expansion coefficient, density, etc. of the material to be analyzed. These physical quantities must be measured in advance, e.g. by experiment. - Analysis
Structural analysis softwares are performed by repeating the process of moving forward in time slightly, changing one element at a time, moving forward in time again, and changing again, until the desired time is reached. The speed of this calculation is determined by computer performance and calculation methods. - Output
Most structural analysis softwares can visualize the analysis results. Visualization allows the user to find displacements and areas of concentrated force in the analyzed object.
Types of Structural Analysis Softwares
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 Methods
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.
