本文就新的动态数据处理方法即时间序列分析方法对机器动态特性进行了探讨。应用时序法的基本原理将AR模型延拓为具有时域模态迭加形式的指数多项式模型,并依据滤波器输出信噪比的特点,确定了AR模型最终阶次的审定方法,同时结合录音机机芯的抖晃特性进行了研究。
In this paper, the new dynamic data processing method, namely the time series analysis method, is used to discuss the dynamic characteristics of the machine. Applying the basic principle of timing method, the AR model is extended to an exponential polynomial model with superposition of the time-domain modal. According to the characteristics of the signal-to-noise ratio of the filter output, the validation method of the final order of the AR model is determined. Jitter characteristics of the movement were studied.
