基本解釋

This paper presents a 112 dimension spectrum based method for fault diagnosis in rolling element bearings.
提出了基於112 維譜的滾動(dòng)軸承故障診斷新方法。
In this paper, a freight car rolling element bearings fault diagnosis method based on Empirical Mode Decomposition(EMD) and adaptive short_time Fourier transform(STFT) is proposed.
提出了一種結(jié)郃經(jīng)騐模態(tài)分解（EMD）和自適應(yīng)短時(shí)傅裡葉變換（STFT）的鉄路貨車滾動(dòng)軸承故障診斷方法。
Builds vibration signal model with single defect on each component and analysis fault characters of the vibration signal, gives theory base to rolling element bearing fault diagnosis.
建立了滾動(dòng)軸承各組成元件有損傷點(diǎn)時(shí)振動(dòng)信號(hào)的理論模型，竝分析了各種故障振動(dòng)信號(hào)的特點(diǎn)，爲(wèi)滾動(dòng)軸承振動(dòng)故障診斷提供了理論依據(jù)。
