Having decades of applied Computational Fluid Dynamics (CFD) experience, evaluating the aerodynamic performance of automotive vehicles and trucks, for brands like Honda and NASCAR, and being active members of a professional body that sets industry standards, puts us in a unique position to conduct CFD testing on trucks or aero devices ensuring they meet greenhouse gas (GHG) emission standards.
Lower your R&D spend on physical prototypes with virtual prototypes, expand your capabilities to assess drag, speed and fuel efficiency without the need to conduct as many expensive physical tests, and enhance efficiencies by automating workflows. No matter your specific goal, TotalSim thrives on solving the most complex aerodynamic challenges.
Tap into one of our many services tailored for the semi-truck industry including:
CFD compliments or in many cases can replace the need for physical testing like wind tunnel or track testing.
R&D through wind tunnel testing can be costly and time consuming. Using CFD to improve designs during development is an efficient route to first prototypes for physical testing. Through our CFD consulting services we have helped many companies accelerate their design process – and we can do the same for you.
We can help in all areas of commercial vehicle design including:
We have a strong background in wind tunnel and physical testing and can provide guidance on whether it is appropriate or needed relative to a specific design. Contact us to review your specific situation.
We provide certification testing for the California Air Resources Board (CARB) Tractor-Trailer Greenhouse Gas (TTGHG) Aero Device Approval program.
The TTGHG program requires the reduction of greenhouse gases on all heavy-duty tractors that pull 53-foot or longer box-type trailers on California highways with the use of aerodynamic devices or other methods to improve fuel efficiency and requires certification
Visit CARB TTGHG or view the Interim Approval Request Form for Aero Drag Reduction Technologies directly for more information about Aero Device Approval.
Our own Co-founder and Technical Director, Naethan Eagles, has helped shape the procedures the trucking industry has adopted. Naethan serves on three Society of Automotive Engineers (SAE) Committees which focus on everything from fuel economy to road vehicles to automated and connected commercial vehicles.
