In this webinar, we build a full sedan model in Dyad and follow it from first assembly through validation and real engineering studies. The vehicle is built in Dyad’s 3D multibody library. It has double-wishbone suspension defined from hardpoints, slip-based tire models, and a powertrain with an engine map and gear-shift logic. We’ll walk through how the model comes together and how components can be swapped as the study requires.
Next, we validate the model against Project Chrono, an established open-source multibody engine, using the same vehicle definition. We compare static setup and a double lane change maneuver. The results agree closely, and the Dyad model runs significantly faster.
With a validated model in hand, we use it for two applications. The first is an emergency braking controller built from Dyad components and run through the Euro NCAP stationary-vehicle test protocol in simulation. We show how changes to the controller’s trigger point affect the outcome. The second is a large parameter sweep on GPUs, running thousands of full-vehicle simulations to see how the best gearing choice changes with road grip.
What You’ll Learn
Full-vehicle modeling: build a sedan in Dyad’s 3D multibody library with hardpoint-defined double-wishbone suspension, slip-based tires and a powertrain with engine map and gear-shift logic.
Validation: compare static setup and a double lane change against Project Chrono using the same vehicle definition.
Emergency braking: run a Dyad-built AEB controller through the Euro NCAP stationary-vehicle protocol and tune its trigger point.
GPU parameter sweeps: run thousands of full-vehicle simulations to find how the best gearing changes with road grip.
Who Should Attend
The session is for engineers working on vehicle dynamics, chassis controls, or ADAS who want to see how far a single Dyad model can go, from component-level modeling to large-scale design exploration.
