Increase Productivity with Easy to Change Attitudes

Considering a vehicle’s performance at different attitudes plays a crucial role in its aerodynamic development. Knowing how the flow structures change with different ride heights, yaw conditions and steering angle, is key to developing a vehicle that operates efficiently over a range of conditions.

However, updating a vehicle’s attitude in CAD and then creating the CFD model can be a complex and time consuming activity. For that, we have developed a crucial tool to speed up this process, the bramble kinematic model.

bramble kinematic model settings

The bramble kinematic model lets users update vehicle attitudes without manually changing the CAD geometry. Our kinematics have an extensive library of different suspension geometries and can even handle other use-cases such as yaw, roll and pitch of a vehicle.

Each kinematic model needs a different set of entries from the baseline geometry. A front wing pitch model needs two points to define the rotation axis for instance, while a double wishbone suspension would need more parameters for each component.

Once configured, you can run any attitude simply by modifying parameters in the map tab. This is where we tell bramble the attitude or attitudes that we wish to test the vehicle over.

Next step, run aero maps

bramble‘s kinematics is the first step to creating aero maps, a crucial tool for motorsport development. You can find more details in this earlier blog post; How to Run an Aero-Map in CFD
