摘　　要：以三环式内平动齿轮减速器为研究对象,采用现代振动信号分析处理的理论方法,对不同转速下采集到的振动加速度信号进行分析,得到了时域参数、自相关函数、功率谱密度函数以及系统的前十阶固有频率。结果表明随着运转速度的增加振动幅度越来越大,且X、Y轴方向上的振动幅度大于Z轴方向上的振动幅度;系统的主要振动频率约在17 Hz、19 Hz、21 Hz和23 Hz处。In this paper,taking three-ring parallel moving gear reducer as the research object,using the method of modern vibration signal processing technique,vibration acceleration signal collected was analyzed under different revolving speeds.Then,time domain parameter,autocorrelation function,power spectral density function and first ten orders natural frequency of the system are obtained.The results show the vibration is increasing with the run speed increases,the magnitude of the vibration in the X and Y direction is greater than that of the Z axis direction,and the main vibration frequency are at the positions of 17 Hz、19 Hz、21 Hz and 23 Hz.
