摘要
在随机共振基础上,提出变化系统参数检测方法,适应高频率检测信号。理论分析、数值仿真表明该方法在碰摩故障早期检测上的可靠性和有效性。
Based on stochastic resonance, varied parameter methods are proposed. The theoretical analysis and numerical simulation manifest that high frequency signal can be detected. The method is reliable and effective in application of the rub-impact fault detection.
