An improved particle swarm optimization (IPSO) algorithm was proposed to identify the dynamic parameters of the vertical mill system. Firstly，the stiffness and damping of the vertical system were considered as the Duffing oscillators and Vanderpol oscillators，and the nonlinear dynamic model of the vertical system was constructed. Then the PSO algorithm was improved，and the dynamic parameters of the system were identified by numerical simulation examples with noise or not，which verified the effectiveness of the algorithm. Finally，the vertical system was taken as the research object，and the algorithm was used to identify the vertical mill system dynamics parameter based on the measured data. Comparing the measured displacement，velocity and acceleration signal respectively with the identified displacement，velocity and acceleration signal，reliability of the method to identify vertical system dynamics parameters has proved. Additionally, the method has certain value in the field of engineering applications.
