The nonlinear dynamic model of the damper was established by fitting the test data. The simulation of the central dynamic behavior of the hub with the nonlinear dynamic characteristics of the damper was simulated. The comparison between the simulation results and the experimental results shows that the non-linear dynamic model of the hub can be predicted more accurately by using the nonlinear model of the damper. The influence of the nonlinear dynamic characteristics of the damper on the dynamic characteristics of the hub is analyzed.
