The invention belongs to the technical field of large high-frequency vibrating grinding and discloses a parameter determining method of a multi-vibration excitor driven large high-frequency vibratingmill. A kinetic model of the vibrating mill comprises a main vibrating system and a vibration isolating system, the center axes of the main vibrating system and the vibration isolating system coincidewith each other, and the main vibrating system and the vibration isolating system are connected through springs; the main vibrating system is composed of a mass body m1 and vibration excitors on themass body m1; the n vibration excitors are uniformly distributed circumferentially around the mass center of the mass body m1 of the main vibrating system; the vibration isolating system is composed of a mass body m2 and vibration excitors, wherein the mass body m2 is connected with the mass body m1 through a set of springs and connected to a foundation through springs; the k vibration excitors onthe mass body m2 are uniformly distributed circumferentially around the mass center of the mass body m2 likewise; (n+k) motors fixedly connected to the two mass bodies rotate in the same direction; and by applying a vibration synchronization theory and obtaining the synchronization and stability conditions of the systems, parameters of the vibration excitors and the vibrating systems are determined, reasonable operating points of the model are obtained, in addition, a theoretical basis is provided for a vibration synchronization problem of practical vibration systems in engineering, and the engineering application value of the parameter determining method is achieved.
