Innovation and collaborative, synchronized program management for new programs
Strict emissions regulations are placing increased importance on efficient aerodynamic design. Getting the design right as early in the process as possible will not only affect overall packaging, but the brand image too. Our best-in-class 3D CFD capability will help you understand the aerodynamic impact of design changes as you pursue increasingly tough performance targets.
Explore the key areas of this solution.
Aerodynamic design is no longer limited to the upper echelons of motorsport or even exotic road cars. Worldwide harmonized Light vehicles Test Procedure (WLTP) places stringent objectives on vehicle performance teams to lower emissions and increase fuel economy, or increase hybrid vehicle range. This makes target-setting for aerodynamic drag a fundamental concern. Refining the shape of the vehicle has a knock-on effect to many other aspects of the design and the overall image of the brand, so analyzing the aerodynamic attributes early on in the vehicle design process is critical to success.
Our solution helps you investigate and understand all aspects of the airflow around the vehicle by offering best in class 3D CFD tools. This allows direct measurement of drag force for fuel economy and lift force for stability, and if further refinement is sought, automatic shape optimization.
Delve deeper into understanding complex behavior using mesh motion to study flow from rotating treaded tires, flow induced noise sources for acoustic issues, or aspects of cooling drag coupled to either 1D or 3D heat exchange models. Our solution will not only help you achieve more efficient aerodynamic designs, but increase your understanding of the effects they cause.
With the shift to improved procedures for fuel consumption and CO2 emissions, a new Worldwide Harmonized Light Vehicle Test Procedure (WLTP) has been developed by the United Nations.
The aim of WLTP is to more accurately reflect real-world driving and harmonize emissions testing across the globe. For vehicle aerodynamics specifically, there is a higher burden on design and testing as engineers now have to move beyond baseline drag and consider all available vehicle configurations.
As the power required to overcome drag rises with the cube of velocity, the faster you go, the more fuel you use. To maximize the driving range of a vehicle, reducing drag is important. This blog looks at some of the numbers behind the problem and the tools available to solve it.
