EN In this paper research results of ability vibration's suppression steel and composite leaf springs were presented. Polymeric composite leaf springs and steel were studied. Composite leaf springs were made from epoxy-glass composite reinforcement by glass fibre. Composite springs became designed to can replace steel spring of van. Executed investigations base on dynamic loadings of leaf springs and registering of vibrations amplitude and reaction of props. Load was realized through lowering from definite height of mass which hit into spring wresting it from balance. Mass stayed on spring to total atrophy of vibrations. Measured and registered parameters permitted to count logarithmic decrement suppressions of tremblings and coefficient of suppression of tremblings. This coefficient was counted for composite and steel leaf springs. Basic exploational parameters of leaf springs were compared as well as basic advantages of applying to vehicles building of composite materials were analysed. Analyses lead to conclusion that composite leaf springs in comparison to steel springs: about three times better suppress of tremblings, they are about five times lighter and give smaller dynamic burdens of vehicles body. Wide applying of composites materials on carrying structures of vehicles will contribute to lower of vehicles mass and to decrease of emission greenhouses gases.
