The variations of ground motion acceleration amplitude ratios(acceleration at a depth to a corresponding amplitude of the surface,Ad/A0 and amplitude of the vertical-to horizontal-component,Av/Ah) with depth are evaluated by considering mainly the influences of component direction and magnitude of the earthquakes.
为了明确地下地震动幅值的衰减规律,基于日本最近几年发生的16次强烈地震的443组深井地震动记录,主要考虑分量方向和震级的影响,分析了地下深层(-100~-400m)地震动加速度幅值与地表对应幅值比(Ad/A0)以及竖向与水平向加速度幅值比(Av/Ah)沿深度的变化特征。

First, the original signals were decomposed into a number of IMFs (intrinsic mode functions): then, the ratios of amplitudes in the characteristic frequencies were defined as the characteristic amplitude ratios after the envelope spectra of some IMFs inc.
该方法首先采用经验模态分解将原始信号分解为若干个平稳的固有模态函数之和,然后求出包含主要故障信息的若干个固有模态函数分量的包络谱,再定义包络谱中故障特征频率处的幅值比为特征幅值比,最后以特征幅值比作为故障特征向量,输入神经网络,以神经网络的输出来判断滚动轴承的工作状态和故障类型。
