MODELING AND AERODYNAMIC SIMULATION OF THE PASSENGER VEHICLE

Abstract

Today, the vehicle aerodynamics has a significant place in the development of vehicle shape, as well as in increasing competitiveness in the automotive market. Aerodynamics has a big influence on improving the vehicle dynamics, reducing fuel consumption, increasing transverse vehicle stability, and increasing vehicle safety during the braking. The development of computer technology made it possible to detect the defects of a product in the early stages of development. This further aims at achieving a shorter time for creating a new one or modifying an already existing product. The simulation of the air flow effects is presented in the paper, using the ANSYS software package. Furthermore, an overview of the impact of the angle of the windscreen on the loads occurring on the vehicle itself is given, in order to improve the vehicle performance.
