摘　　要：基于振动响应传递率的工作模态分析方法(operational modal analysis,OMA)相比于传统的试验模态分析方法(experimental modal analysis,EMA)不需要激励被测系统,因此具有测试步骤简单,应用场景广泛的优点。但当前基于振动响应传递率的工作模态分析方法还处于起步阶段,暂未形成统一的理论体系。为此,梳理和总结了基于传递率的工作模态分析方法的有关研究成果,并将其应用于光学精密设备的模态测试之中。Compared with the traditional experimental modal analysis,operational modal analysis based on the vibration response transmissibility does not need to excite the measured system.So it has the advantages of simple test steps and wide application.However,the current operational modal analysis method based on the vibration response transmissibility is just in its start-up step up to now,and the unified and orderly theory system has not formed.This paper shows the theory system and the research achievement of the operational modal analysis based on the vibration response transmissibility,and used it in optical precision instruments.
