探索复杂行星轮系故障诊断方法。对振动信号作功率谱分析,提取故障特征,并基于ART-2神经网络提出行星轮系故障模式识别方法。该方法不仅能够对待检工况的模式作出正确的判断,而且对未知模式具有较强的自适应分类能力,通过实例分析验证方法的可行性。
A fault diagnosis method for the complicated planetary transmission is explored. Through power spectrum analysis for the vibration signals, fault features are picked-up, and a method of fault paltem classification for a planetary transmission based on ART-2 network is presented. This method is not ouly able to judge the patterns for the examined states correctly, but also provided with better ability of adaptive classification for the unknown pattern. The validity of this method has been validated through an example.
