Nonlinear analysis of a 4-dof friction induced self-ocsillation system with the friction coefficient of velocity and pressure

속도와 압력의 항의 마찰상수를 갖는 마찰기인 4자유도계 자려진동 시스템의 비선형 해석

Four degrees of freedom mathematical model is presented to describe the fundamental mechanisms of the disc brake squeal noise. A contact parameter is introduced to describe the coupling between the in-plane and the out-of-plane motions. The friction coeficient including "relative velocity" and ′normal force" can be generally formulated as the form of multiplication with polynominal parameters(${\beta}$, ${\gamma}$). (omitted)
