| 摘 要： | 针对变速齿轮在某一转速范围内运行时产生共振导致强烈振动的问题,有效地对变速齿轮啮合频率进行评估是减少和规避此类故障的关键。但由于变速齿轮振动信号在时域呈现非平稳性,传统的齿轮信号分析方法无法有效地提取出特征频率,并且齿轮箱振动源较多且存在背景噪声,导致阶次谱成分复杂。有鉴于此,将阶次跟踪和经验模态分解相结合,提出一种基于阶次跟踪的变速齿轮啮合频率振动评估方法。首先采用阶次跟踪方法对某转速下齿轮的时域信号进行等角度重采样;然后对阶次域信号进行经验模态分解,提取出包含齿轮啮合信息的本征模函数(Intrinsic Mode Function,IMF)分量;再利用阶次谱分析提取出齿轮啮合阶次所对应的幅值;最后通过比较不同转速下的齿轮啮合阶次的幅值大小,对齿轮的振动变化进行评估。在实际现场齿轮信号的应用结果表明:该方法得到的阶次谱中啮合阶次明显,并且能够有效地实现变速齿轮的共振转速识别。
