This guide will explain how the MS14 simulations should be set up to simulate the regulation impact scenarios.
There are 13 scenarios that need to be simulated:
- Front impact (bar)
- Rear impact (bar)
- Side impact (bar)
- A-pillar impact (wall)
- B-pillar impact (wall)
- C-pillar impact (wall)
- Side 30 degree impact (wall)
- Side 60 degree impact (wall)
- Front 30 degree impact (wall)
- Front 60 degree impact (wall)
- Top 30 degree impact (wall)
- Top 60 degree impact (wall)
- Top impact (wall)
Before you start ANSYS, you should have these CAD models ready
- Steel chassis
- Composite catamaran
- Impact objects (All 13 impact objects should be combined into one file for convenience)
ANSYS
- Import the geometries into the ANSYS workbench
- Import the line bodies for the chassis and create beam elements in DesignModeler → TUTORIAL: ANSYS - Beam Elements
- Import the surface bodies for the catamaran in DesignModeler
- Import the solid bodies for the impact objects in SpaceClaim, and make necessary changes to the model
- Here, all of the impact objects are combined in one model. In the simulations, we will suppress the unneeded objects instead of having a separate model for each object.
- Set up the catamaran geometry in ACP (Pre) → TUTORIAL: ANSYS - ACP (Pre)
- Combine the geometries of the chassis and the catamaran into one model
- In Mechanical for the chassis and catamaran, right click on Connections then Insert>Connection Group
- In your connection group properties, Face/Face, Face/Edge, and Edge/Edge should be all changed to Yes
- Right click on your Connection Group folder icon and then Create Automatic Connections
- Open your Connection Group folder and check if all the necessary connections have been made
- In this picture we can see that the front portion of the chassis has been connected to the front panel of the catamaran
- If there are missing connections, right click on Connections then Insert>Manual Contact Region
- I added a contact region between the bottom edge of the chassis to the edge of the catamaran
- Generate your mesh and then your chassis/catamaran is ready for an Analysis System
- Your workbench should now have 2 mechanical models, one with the chassis and the catamaran, the other with the impact objects
- Now you can add an Analysis System, connect the chassis/catamaran model and the impact object model to the Analysis System
- You will have all of the impact objects in your model, just suppress the impact objects that you do not need
- Add ACP (Post) after the Analysis System for catamaran analysis → TUTORIAL: ANSYS - ACP (Post)
- Now you can keep adding Analysis Systems and connecting both models to them (repeat steps 13 and 14)
