针对提高变分模态分解(Variational Mode Decomposition,VMD)的自适应性、优选本征模态分量(Intrinsic Mode Function,IMF)及多故障分类的问题,提出一种天鹰优化器(Aquila Optimizer,AO)优化VMD、综合评价模型优选IMF、改进天鹰优化器(Improved Aquila Optimizer,IAO)优化支持向量机(Support Vector Machine,SVM)的齿轮箱故障诊断方法。首先,采用AO优化VMD的参数并分解原始信号;其次,构建基于相关系数、峭度、包络熵、能量熵的CRITIC-TOPSIS综合评价模型,优选IMF,提取能量熵建立特征向量;最后,将其输入IAO-SVM识别故障类型。通过实验验证所提出方法的有效性。
Aiming at the problems of improving the adaptability of variational mode decomposition (VMD) and in order to optimize the intrinsic mode function (IMF) and multi-fault classification
a gearbox fault diagnosis method is proposed
with which the Aquila optimizer (AO) optimizes VMD
the comprehensive evaluation model optimizes IMF
and improves the Aquila optimizer optimization support vector machine (IAO-SVM). Firstly
AO is used to optimize the parameters of VMD and decompose the original signal. Secondly
a CRITIC-TOPSIS comprehensive evaluation model based on correlation coefficient
kurtosis
envelope entropy
energy entropy is constructed to optimize IMF
and energy entropy is extracted to establish feature vectors. Finally
it is input into IAO-SVM to identify faults. The effectiveness of this method is verified by experiments.
