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
- 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 ToolBar, click (+) and then Library. Within the OnScale Library, Select Tactile Switch.
- Using either the Model tree or the 3D viewer, select Leg 1, Leg 2, Leg 3, Leg 4 and Cover.
- From the Material dropdown in the properties panel, assign Aluminum to these five parts.
- Using either the Model tree or the 3D viewer, select Body and Button.
- From the Material dropdown in the properties panel, assign Acrylic Plastic to these two parts.
Add a fixture
- Select the tab.
- In the toolbar, ensure that the Mechanical Physics tab is on.
- Select Restraint as the constraint to fix the appropriate surfaces for the study.
- Using either the Model tree (preferably) or the 3D viewer, select the Bottom Left and Bottom Right faces within the Body of the assembly.
- Ensure that the restraint type is a fixture in the right hand panel.
- Then select Done.
Add a force load
- Select Force in the toolbar to add a force load.
- Using either the Model tree or the 3D viewer, select Button Center Face which is located within the Button part of the assembly.
- In the properties panel, hover the mouse over the Force input box to assign a load to this face.
- Click the symbol
- Set the Start Value to 0.1, End Value to 1 and Number of Values to 10.
- Click Done and click Done again, in the properties panel.
Run a simulation
- Select the simulator tab.
- Click on the Launcher to run the simulation.
- You should see a queue for 10 simulations scheduled to run in parallel.
- Once the meshing and estimation is complete, Select Launch to run the simulation study.
Analyze the results
- Once the simulation has finished, select Load Results to open the results in the Results tab.
- There is a wide range of output categories to choose from. Select Displacement from the options
- In the properties panel, click on the direction arrows to view the various results for the different load parameters.
- View the results for the 6th load parameter. Do you get a maximum displacement equal to 66.51 mm?
