The present invention discloses a sliding bearing system dynamic property analysis method. The method comprises the steps of: obtaining a frequency-response function matrix of a substrate system as adynamic property function of the substrate system; obtaining a dynamic property coefficient of a sliding bearing supported on the substrate system; and performing analysis of the dynamic property of asliding bearing system according to the dynamic property coefficient of the sliding bearing and the frequency-response function matrix of the substrate system, wherein the sliding bearing system comprises a rotor, the pedestal system and the sliding bearing supported on the substrate system. The method can achieve accurate analysis of the influence of the substrate on the dynamic property of thesliding bearing system on the premise of conveniently and accurately reflecting the dynamic property of the pedestal. The present invention further discloses a sliding bearing system dynamic propertyanalysis device and system and a readable storage medium which have the effects mentioned above.
