Sažetak
Nowadays, there are many software packages which make it easy for students and engineers to display and describe an imaginary idea in better quality, in better sense and in shortest possible time. Therefore, car is designed using the software package Autodesk 3ds Max. Polygonal modeling method was used and designed car represent a new conceptual solution car design. After modeling a car in mentioned software, final digital images are generated too. Final digital images are generated using the Mental Ray rendering tool as a default rendering tool of Autodesk 3ds Max. Attention is given only to the external design of the car, while the interior is not modeled. Furthermore, using the software Ansys Fluent, 2D simulation of the airflow around the side contour of the vehicle was made in purpose of making changes in the geometry of the vehicle to improve the design in terms of reducing air resistance and improve aerodynamics. Most attention of this is given in changing value of angle between the hood and front windshield of car, and analyzing back of the car with and without the rear wing. Also, using the software Ansys CFX, 3D simulation of airflow around the car geometry was made too. Taking into consideration results obtained by 2D and 3D analysis of existing car geometry, a new 3D car model was made. Assumption is that new 3D car model is resulting with better aerodynamic properties. 3D analysis of redesigned car model in terms of mentioned changes is performed too in order to analyze possible improvements.
