CAE Driven Aerodynamic Analysis for Car Body Design

Posted by: | Posted on:

The automotive industry thrives on innovation, and there are so many new, fuel efficient and sleek car designs flooding the market. In such a highly competitive environment, automobile manufacturers are constantly driven by the need to improve designs. However, design optimization using the conventional ‘prototyping and testing an automobile for aerodynamics’ involves, building a detailed model of the vehicle, and testing it in a wind tunnel. Collecting aerodynamic information and iterating designs in this manner is extremely costly. If the prototype is scaled down and tested, there is a risk that the results might not be accurate.

Using advanced simulations for aerodynamic analysis of a vehicle body, allows design iterations and validation at an early stage. Evidently, advanced simulations and their wide range of applications across the automotive design and manufacturing processes have enabled engineers to experiment more. This is the key driver for innovation in the field of automobile design and development.

Aerodynamic Analysis for Vehicles to Perform Better

Vehicle aerodynamic analysis plays a critical role in optimizing the vehicle body design for better performance. The most crucial benefits of an aerodynamic design is better speed and fuel efficiency through less friction and less wind drag. Other benefits include better vehicle stability, and reduced noise & vibrations. The most basic aerodynamic design and analysis allows automobile designers to optimize the shape, proportions, styling and passenger space of a vehicle. As the vehicle, engineering using aerodynamic analysis capabilities progresses further it also helps evaluate and validate the design of spoilers, deflectors and under body covers. Another very important aspect of car body design and aerodynamic analysis is that adequate cooling flow to the heat exchangers should be maintained.

As discussed earlier, aerodynamic analysis via advanced simulations has proven benefits over the conventional prototyping and testing techniques. Using computational methods for design and validation, reduces both the vehicle development costs and the design cycle time. By duplication the actual on road conditions via simulation, aerodynamics for a car body can be designed without compromising the durability, safety and occupant comfort of an automobile.
