The weight decreasing of small cars can be very effective by using of lightweight materials. Movable masses of such cars like suspension arms, wheel rims, drive shafts can be made of magnesium alloy, brake discs can be made of aluminum alloy. Such masses can mate with electromagnetic shock absorbers with possibility of recuperation for energy of chassis vibrations, changing it into the useful electric power. Main parts of the shock absorber are the cylinder with the set of coils and the rod with a set of permanent magnets. Cylinder can be made of magnesium alloy. Coils winding has been connected to electric wires placed inside light spring. Three-phase current generated in the set of coils can be supplied through the controlled rectifier into battery. Dimensions of electromagnetic shock absorber have been close to those of hydraulic shock absorber, so it can be used in the typical chassis of automobile. The scheme of the shock absorber has been shown in the article. The elaborated model of road roughness and of moving masses for small car, connected to electromagnetic shock absorber has been shown in the article. It has been analysed the values of dynamic parameters during operation of electromagnetic shock absorber with movable masses of small car driven in different road conditions. Results of such analysis have been presented in the article. The aim of the study has been to estimate and to compare the amount of recuperated energy by the electromagnetic shock absorber – rectifier – battery assembly for the cases of car movable masses made of steel and for the one of lightweight materials
