摘要

摘要: 阐明了工况传递路径分析方法(Operational Transfer Path Analysis, OTPA)的基本原理和分析流程;基于单路径隔振系统进行传递函数计算和精度分析;利用OTPA方法对3路径隔振系统的每条路径进行振动传递能力分析,并利用路径的振动传递贡献量确定出振动传递的关键路径。分析方法和流程能为机械系统振动或噪声源定位、传递机理分析、振动或噪声控制提供研究基础。

Abstract: The fundamental and analysis process of the operational transfer path analysis method are clearly illustrated firstly; based on the single path isolation system, the transfer function of transfer path is calculated and its accuracy is analyzed; At last, the vibration transmission capacity of each path of a three-paths isolation system is analyzed by OTPA method, the critical path of vibration transmission is determined using contribution analysis of vibration transmission. The method and process of analysis can provide the research foundation for vibration or noise source localization, transfer mechanism analysis, and vibration or noise control.
