摘要

传递路径分析方法(Transfer Path analysis, TPA)是当前诊断机械系统振动和噪声最通用的手段。本文介绍了传统TPA、工况TPA、OPAX、快速TPA、多级TPA以及混合TPA的基本原理和优缺点,结合实例说明实现过程,并进行综合比较得出各种方法的应用场合,最后对TPA方法的未来发展做了展望。

Abstract

Transfer path analysis (TPA) is now the most common tool in noise and vibration diagnosis of mechanical system. A review of frequency-domain TPA methods is presented, which include conventional TPA, OPA, OPAX, fast TPA, multilevel TPA and hybrid TPA. The basic principles and advantages and disadvantages of the above methods are introduced. In addition, operational methods of these methods are illustrated with several examples and application areas of the methods are summarized based on the comprehensive comparison of these methods. Finally, the remained problems in current TPA methods are also discussed with some suggestions given for future study.
