Abstract
The 3D-model of an air spring for road vehicles is presented. A virtual calculation of the air spring has been carried out. Calculation results have been analyzed for adequacy by investigating grid deformation and checking pressure inside the rubber part of the air spring. The most dangerous places of the air spring are shown. Possibilities of LS-Dyna software package for engineering analysis are demonstrated. The influence of computer-aided design systems on modern engineering solutions is considered.
