摘要

本文描述了非比例阻尼在颤振型失稳中的作用，并在简化的盘式制动器模型上进行了论证。通过系统特征值评估，离散两自由度系统被认为意味着阻尼引起的不稳定性。频率响应函数（FRF）是根据物理盘式制动器模型上的测量值进一步计算得出的。根据FRF，对阻尼特性进行了估计和讨论。衬垫与圆盘的几种不同加载状态被认为显示了对FRF的加载影响，从而显示了系统的阻尼。

Frequency Response Function Measurement on Simplified Disc Brake Model

Abstract The paper describes role of non-proportional damping in flutter type instability, demonstrated on simplified disc brake model. The discrete two degrees of freedom system is considered to imply damping induced instability through a system eigenvalues evaluation. The Frequency Response Function (FRF) is further calculated from measurements on the physical disc brake model. From FRF, damping properties are estimated and discussed. Several different loading states of the pad versus disc are considered to show loading impact on FRF and thus damping of the system.
