Abstract

Aerodinamika je jedan od najsloženijih dijelova inženjeringa i dizajna automobila. Aerodinamika u svom poimanju povezuje sve fizičke poveznice, a istraživati i proučavati njezino načelo na objektu automobila danas je vrlo popularno. Postoji nekoliko faktora koje treba promatrati u aerodinamici vozila. Prvi je tlak, koji djeluje normalno na površinu, a drugi je posmična sila. Smično naprezanje u tekućini postoji samo kada je tekućina u pokretu, za razliku od čvrstih tijela koja se mogu oduprijeti smicanju u statičkim uvjetima. Određeni faktori poput dodataka iznad stražnjih svijetla (razna krilca) ili nabora na karoseriji pomažu da vozilo klizi kroz zrak. Također oblici i veličine bočnih retrovizora ključni su za postizanje boljih aerodinamičkih uvjeta. Sukladno napretku u razumijevanju fizike i aerodinamike, kao i računalnom izračunu i modeliranju, automobili su sve bolje iskorištavali svoj oblik kako bi smanjili potrošnju i povećali svoju aerodinamičku efikasnost.

Abstract (english)

Aerodynamics is one of the most complex parts of automotive engineering and design. Aerodynamics in its concept connects all physical links, and researching and studying its principle on the object of a car is very popular today. There are several factors to consider in vehicle aerodynamics. The first is pressure, which acts normal to the surface, and the second is shear force. Shear stress in a fluid only exists when the fluid is in motion, unlike solids that can resist shear under static conditions. Certain factors such as taillight additions or body creases help it slide through the air. Also, the shapes and sizes of the side mirrors are key to achieving better aerodynamic conditions. In line with advances in the understanding of physics and aerodynamics, as well as computer calculation and modelling, cars have increasingly taken advantage of their shape to reduce consumption and accelerate their aerodynamic efficiency.
