基于声发射的RT轨道机疲劳加载信号特征提取与分析

摘要

本文在不同应力条件下对RT轨道机进行疲劳加载，采集RT轨道机从加载到断裂时的信号，对信号进行时域和频域分析观察信号特征对RT轨道机断裂原因进行探讨。%In this paper, under the condition of different stress fatigue load of RT rail machine, acquisition RT track machine from the load to the fault signal and about the signal in time and frequency analysis to observe the signal characteristics of RT rail machine and discuss the fault reasons.
