Abstract
U radu je napravljen proračun i analiza postojećeg MacPherson prednjeg ovjesa osobnog automobila. Poznati su neki podaci o automobilu i karakteristike opruge. Temeljom tih podataka određena je geometrija ovjesa automobila i optimirana debljina opruge žice. Zadatak je ovjesa automobila maksimizirati trenje između pneumatika i površine ceste, osigurati stabilnost pri skretanju s dobrim držanjem i osigurati komfor putnicima. Ispupčenja na cesti uzrokuju kretanje kotača gore i dolje okomito na površinu ceste i kotač automobila dobiva vertikalno ubrzanje. Bez ovjesa, sva se energija s kotača prenosi na okvir koji se kreće u istom smjeru. U takvoj situaciji, kotači mogu izgubiti kontakt s cestom u potpunosti. Zatim, pod djelovanjem gravitacijske sile, kotači mogu udariti o površinu ceste. Da bi se to izbjeglo potreban je sustav koji će upiti energiju uzrokovanu vertikalnim ubrzanjem kotača, dopuštajući okviru i tijelu automobila neometanu vožnju dok kotači prate ispupčenja na cesti. Prema proračunu je izrađen 3D model ovjesa u softveru SolidWorks, koji je zatim učitan u softver ANSYS kako bi se napravila numerička analiza i optimizacija.
Abstract (english)
In this paper are made calculation and analysis of existing MacPherson front car suspension. Some car data and spring characteristics are known. Based on these data car suspension geometry and optimized spring wire thickness are defined. The job of a car suspension is to maximize the friction between the pneumatics and the road surface, to provide steering stability with good handling and to ensure the comfort of the passengers. Bumps in the road cause the wheel to move up and down perpendicular to the road surface and the car wheel experiences a vertical acceleration. Without a suspension, all of wheel's energy is transferred to the frame which moves in the same direction. In such a situation, the wheels can lose contact with the road completely. Then, under the downward force of gravity, the wheels can slam back into the road surface. To avoid that, a system that will absorb the energy of the vertically accelerated wheel is needed, allowing the frame and body to ride undisturbed while the wheels follow bumps in the road. Based on calculation, a 3D model of suspension is made in software SolidWorks, which is then imported in software ANSYS in order to make numeric analysis and optimization.
