| 摘 要： | To analyze the modeling methods of the dry friction rotor system, a local linearization model of the dry friction damping rotor system was built based on the simplified model of the wave-shaped steel-belt supporting rotor system. In this model, the linear stiffness of damper closed to pre-deformation was defined as the stiffness of damper, the maximum amplitude of the rotor was calculated according to the load and linear rotor, and the damper＇s parameters were defined on the basis of the energy dissipation parameters. The presented method can reflect the hysteresis characteristics and is easy to calculate. Experimental results demonstrate the accuracy and feasibility of this method.
