Hi-Tech provides computer aided simulation services for automotive exterior using Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA). We address complex engineering challenges faced by designers and manufacturers in developing streamlined outer body design to outperform against drag forces.
Hi-Tech’s CAE expertise in Automotive Exterior Analysis:
Outer body contributes to the total drag by around 60%; hence a fairly large concentration has to be laid on its streamlining. To develop the exterior design with minimized drag, Hi-Tech offers CFD analyses that include:
Drag, Lift and Moment Analysis which provides assistance to engineers in developing exterior design that accommodates smooth streamlined air flow, reduces the drag force and improves handling characteristics. The analysis also helps in determining proper layout of fenders as well as aesthetic lines on the sides of the vehicle to avoid air flow impairment.
Vortex Analysis to determine and eliminate the intensity of vortex flows around the “A” pillar, rear of the vehicle, underneath the vehicle and around the wheels to minimize its negative impact on vehicle dynamics.
Computational Aero Acoustic Analysis (CAA) which helps in analyzing generation of noise due to turbulent flows over the automotive exterior. This analysis assists in optimizing windshield angle and rain gutter position to minimize noise generation and its transmission inside the cabin.
