In this paper, results of research on vibration suppression in steel and composite leaf springs are presented. Polymeric composite leaf springs and steel springs are studied. Composite leaf springs were made of an epoxy-glass composite reinforced with glass fibre. Composite springs were designed in such a way that they could replace steel springs in a van. Static and dynamic examinations of both the springs were performed. The amplitude of vibrations and the reaction of props were measured and recorded. These parameters rendered it possible to calculate the logarithmic decrement of vibration suppression and the coefficient of vibration suppression for steel and composite leaf springs. The results are presented in tables and graphs. It is concluded that composite leaf springs in comparison to steel springs about three times better suppress vibrations , they are about five times lighter and generate smaller dynamic burdens to vehicle bodies.
