Tactile Switch – Parametric Sweep FEA
This simulation tutorial will guide you through:
- Applying a force load to a tactile switch
- Adding a parameter to a load
- Running a simulation
- Viewing the displacement in the simulation results
Import the CAD file
- In OnScale Solve, from the Projects tab of the dashboard, create a new project.
- In the Tool Bar, click (+) and then Library. Under OnScale Library, Select Tactile Switch.
- Select Millimeters as the length unit.
- Using either the tree or the 3D viewer, select Leg 1, Leg 2, Leg 3, Leg 4 and Cover.
- Using the Material dropdown in the properties panel, assign Aluminium to this part.
- Using either the tree or the 3D viewer, select Body and Button.
- Using the Material dropdown in the properties panel, assign Acrylic Plastic to this part.
Add a fixture
- Select the tab.
- In the toolbar, select > to fix the surface.
- Using either the tree or the 3D viewer, select Face 33 and Face 37 under Body.
Add a force load
- In the toolbar, select > to add a force load.
- In the properties panel, for Force, click (hover the mouse over the Force input box).
- Set the Start Value to 0.1, End Value to 1 and Number of Values to 10.
- Click Done and then click Done, again, in the properties panel.
Run a simulation
- Select the tab.
- In the properties panel, select MESH & ESTIMATE. This automatically meshes your model, estimates how long the simulation will take to run, and estimates what the likely core-hour cost will be.
Once the meshing and estimation process has finished, use the cost–time slider to select the level of computational resource that you want to use for this simulation.
- Select RUN to run the simulation.
Analyze the results
- Once the simulation has finished, select Load Results to open the results in the Results tab.
- Output categories can be selected from the tree: Select Displacement.
- In the properties panel, expand the Output dropdown to select Z displacement component
- Click the blue arrow to cycle through the simulation and view the results of each.
