3D Modelling and Aerodynamic Simulation of a Passenger Car

摘要

The shape of a passenger car is very important, both in terms of vehicle dynamics and for winning the leading position on the market. The vehicle's aerodynamics greatly affects fuel consumption, vehicle stability and safety during braking process. Today's software tools make it much easier to develop a new product - a car. This further contributes to the manufacturer to be competitive on the market, as well as reducing the necessary investment in developing a new model of car. The influence of air resistance on the fuel consumption and the occurrence of noise and vibrations, using the ANSYS software package, is analysed in the paper. Then the coefficient of aerodynamics of the vehicle was determined. Also, the loads that occur during the movement of the vehicle and what are the most exposed areas are shown.
