A Study on the Relationship Among Several Friction-Induced Instability Mechanisms Based on Multi-point Contact Nonlinear Dynamical Friction-Induced Vibration Model

摘要

In this paper, according to the topology and contact mode between pad and disk, a nonlinear friction and vibration dynamic model with dual mass and three-degrees-of-freedom is established for a kind of friction and vibration system composed of flexible body-rigid body friction pairs with lumped parameters. By means of mathematical formula derivation and numerical calculation, the following conclusions are obtained:
