The invention aims to provide a design method of a steering system dynamic vibration absorber with simple structure, low cost and convenient installation so as to solve the problem of steering wheel vibration when idling and improve vehicle riding comfort. The steering system dynamic vibration absorber comprises a plate like mounting base and a mass block which are connected by a plurality of rubber columns; by adjusting the mass of the mass block and the rubber column tangential stiffness, the tangential inherent frequency of the dynamic vibration absorber when the dynamic vibration absorber is installed in a steering system is similar to the main exciting frequency when the motor idles; the vibration of the motor when the vehicle idles is transmitted to the dynamic vibration absorber via a steering column or the steering wheel to cause the mass block to carry out sympathetic vibration and convert into heat quantity to be dissipated, thus greatly lowering vibration transmitted to the steering wheel and improving vehicle riding comfort. The absorber has small improvement of the original vehicle, has simple structure, low cost and convenient installation and is suitable for being applied to produced or designed and shaped vehicle types.
