摩擦引起的振动噪声文献综述与研究展望

Literature Survey and Research Prospect of Friction Induced Vibration and Noise

摘要:

摩擦振动和噪声是机械工程领域的研究热点和前沿科学问题之一。本文以制动尖叫这一典型的摩擦噪声为例，从试验研究与分析、发生机理与理论、建模方法与仿真三个方面,对国内外从动力学、摩擦学以及摩擦-动力学耦合的角度所开展的研究进行了文献综述。在讨论研究难点根源和前人研究缺陷的基础上，作者建议考虑系统参数的随机性，开展摩擦噪声不确定性理论的研究。

Abstract:

Friction induced vibration and noise is one of the hottest and the most advanced research themes in the field of machinery engineering. In this paper, a comprehensive technical review on the typical automotive brake squeal has been conducted. It covers the dynamical, tribological, and tribo-dynamical studies respectively concerning experimental investigation and analysis, generation mechanisms and theories, modeling methods and prediction. The author has done the literature survey and discussed the origin of the research difficulties. Looking into the limitations of the previous researches, he proposes that the investigation be directed to the study of the uncertainty of the friction induced vibration and sound, in which the system parameters randomicity should be taken into consideration.
