目的
2
针对滚动轴承剩余寿命预测中存在的振动信号噪声干扰及不同工况下数据分布偏移问题,提出一种结合深度残差收缩网络(Deep Residual Shrinkage Network
DRSN)与对抗式领域自适应(Adversarial Domain Adaptation
ADA)的健康状态评估方法,以提高寿命预测的精度与泛化能力。
方法
2
首先,构建了深度残差收缩网络和对抗式领域自适应健康状态评估模型,并利用DRSN可以规避振动信号中的噪声并自适应提取轴承退化特征的性能,构建了健康指标曲线;其次,利用ADA使测试集健康指标和训练集健康指标分布对齐;最后,将DRSN-ADA模型输出的健康指标输入到卷积长短时记忆(Convolutional Long Short-Term Memory
ConvLSTM)网络模型中,实现了剩余寿命预测。
结果
2
结果表明,在XJTU-SY数据集及工程试验中,DRSN-ADA所构建的健康指标在单调性、鲁棒性和关联性上均优于对比方法,其均值分别达0.61、0.97与0.98;寿命预测结果的均方误差与平均绝对误差均值分别为2.52%与2.19%,平均得分为0.86,显著优于ResNet、主成分分析及均方根方法,验证了该方法在噪声抑制与跨工况预测方面的有效性。
Objective
2
A health state assessment method combining deep residual shrinkage network (DRSN) and adversarial domain adaptation (ADA) was proposed to address the problems of vibration signal noise interference and inconsistent data distribution under different working conditions in the remaining useful life (RUL) prediction of rolling bearings
so as to improve the accuracy and generalization ability of RUL prediction.
Methods
2
Firstly
a health state assessment model combining deep residual shrinkage network and adversarial domain adaptation was constructed. The performance of DRSN in avoiding noise in vibration signals and adaptively extracting bearing degradation features was utilized to build the health indicator curve. Then
ADA was used to align the distribution of health indicators between the test set and the training set
so as to eliminate the difference in data distribution under different working conditions. Finally
the health indicators output by the DRSN-ADA model were input into the convolutional long short-term memory (ConvLSTM) network model
and the accurate RUL prediction of rolling bearings was realized.
Results
2
In the XJTU-SY dataset and engineering tests
the health indicators constructed by DRSN-ADA are superior to the comparison methods in monotonicity
robustness and correlation
with their mean values reaching 0.61
0.97 and 0.98 respectively. The mean values of mean squared error (MSE) and mean absolute error (MAE) of the RUL prediction results are 2.52% and 2.19% respectively
and the average score is 0.86
which is significantly better than the DRN
principal component analysis and root mean square (RMS) methods. These results verify the effectiveness of the proposed method in noise suppression and cross-working condition prediction.
