This stage of FEA is essentially checking over your results to see if they make sense. The most popular are Total Deformation and Equivalent Stress. You can choose from a large array of results to plot. In this section, you can add contour plots to better visualize your model. Note that under Analysis Settings, you can change the duration of the simulation. Make sure the the direction of the force points downwards, which should be the -Y direction. Next, add a Force to the face of the inside of the cylinder where the drone would come in contact with the foot pad. If you are not selecting faces, but instead keep selecting individual lines or the whole body, change the selection mode on one of the top ribbons (lots of mouse pointers and cubes) to face. Note that not all boundary conditions are applicable to each analysis system, for example, we cannot add a voltage to our static structural analysis.įor this part, add fixed supports to the part of the feet that touch the ground (Ctrl click to select multiple faces). There are types of boundary condition including inertial (gravity, acceleration, rotational velocity, etc) which deal with the movement of the body, loads (force, pressure, temperature, radiation, voltage, etc) which usually inolve an external entity acting upon the body, supports (fixed support, cylindrical support, fixed rotation, etc.) which fixes a property of the body, and a few more. Make sure that you are either on "Static Structural" or "Analysis Settings," and now you can start to add boundary conditions. Note that you do not need to exit the Mechanical Window to access setup, it is accessable from the outline window once you click the name of the analysis, in this case, "Static Structural." Once you click on that or any of its subfolders, you may notice that the ribbon directly above the outline window has changed. This part encompasses the actual simulation of your model. The solution section is basically where you can take a break and let the computer do all the heavy work after you do some initial setup. A finer mesh can result in a more accurate model, but it will take more time for the computer to solve, likewies, a coarser mesh will be quicker to use but less accurate.

Next, generate a mesh using the default settings. Expand Geometry until you reach the part you inserted and change the material to ABS Plastic in the details window right below. This section is where the raw 3D model gets subdivided into its elements in a process called meshing and is alo where material assignments take place.Īfter opening the model in ANSYS Mechanical, you will see an outline on the left side. Note that not all file types are compatible with, and that includes a regular SolidWorks part file (.SLDPRT) Right click on geometry and import the file from your computer.

You can either find the Solidworks model of the footpad in SVN and save it as a parasolid (.x_t) or download it here from Drive. This is the section where the raw 3D model will go into.

Add ABS plastic (located under Granta Design Sample Materials) to your project by clicking on the plus sign. The default placeholder material that ANSYS uses is structural steel. To add any new material to your project, open up Engineering Data and click on Engineering Data Sources which is accessable through both the Right Mouse Button and a tab near the upper left corner. This includes the materials and meshed geometry. Pre-processing is the stage where you add essentially gather all the ingredients that you need to run the FEA. It would be helpful if you are somewhat familiar with the ANSYS workspace from these tutorials:īegin by launching ANSYS Workbench and insert a Static Structural analysis system into the project. This tutorial will go through the process of doing a stress analysis on a landing foot used on Spinny. Finite Element Analysis is essentially the process of breaking a model into very small shapes so that a computer can do a ton of math on it to simulate physics.
