Propeller
This simulation tutorial will guide you through:
- Applying a torque load to a propeller blade
- Adding a parameter to a material
- Running a simulation
- Viewing the stress 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 Propeller.
Assign a material
- Using either the Model tree or the 3D viewer, select the Propeller.
- From the Material dropdown in the properties panel, select Aluminum.
- Click on the pencil to edit its properties.
- Under Mechanical properties, click the
symbol in the Young’s Modulus dialog box to allocate a parameter.
- Set the Start Value to 60e9, End Value to 70e9 and Number of Values to 5.
- Under Thermal properties, click the
symbol in the Thermal Conductivity dialog box to allocate a parameter.
- Set the Start Value to 160, End Value to 240 and Number of Values to 10.
- Click Done to save changes.
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 tree or the 3D viewer, select the Inner hub.
- Ensure that the restraint type restrains the x, y, and z axis (in other words, is a fixture) in the right hand panel.
- Select Done in the right hand panel.
Add a Torque load
- Select Torque in the toolbar to add a force load.
- Using either the Model tree or the 3D viewer, select the Second Blade Face and Second Blade Back for the load assignment.
- In the properties panel, enter 1000 Nm as the Torque.
- Switch to coordinate mode to reorient the Torque
- In the Axis of Rotation dialog box, enter 0 for the x-orientation, 1 for the y-orientation, and 0 for the z-orientation.
- Click Done to save changes.
Run a simulation
- Select the Simulator tab.
- Click on the Launcher to run the simulation.
- Once the meshing and estimation is complete, Select Launch to run the simulation study.
- You should have 50 simulations run in parallel. Can you guess why?
Analyze the results
- Once the simulation has finished, select Load Results to open the results in the Results tab.
- Expand the Settings option and toggle Show Mesh on.
- Attempt to filter the results by clicking on Sensors.
- Click Filter results.
- Click on the + to filter results for Parameter 1. Filter values equal to 6.75e10 Pa using the slider.
- Select Save.
- Click on the + to filter results for Parameter 2. Filter values Less than 186.667 W/(m*K).
- Select Save.
- Close the Filter box.
- Click Global Sensor.
- There is a wide range of output categories to choose from. Select the xx component of the Stress from the output datasets.
- What are the maximum stress values for the three filtered results?
