摘要
为解决小样本和变工况下行星轮轴承剩余寿命预测准确率低的问题,提出一种基于条件深度循环生成对抗网络(C-DRGAN)和动作探索(AD)的行星轮轴承剩余寿命预测方法。将门控循环单元神经网络与条件生成对抗网络相结合,构建C-DRGAN,从非静态和非线性信号中提取故障特征,实现小样本和变工况下行星轮轴承的剩余寿命预测;采用基于AD的训练算法训练C-DRGAN,提高收敛速度,降低训练时间;根据训练后的C-DRGAN,利用多元线性回归分类器预测测试样本中行星轮轴承的剩余寿命。通过行星轮轴承加速疲劳寿命试验验证该方法的有效性。结果表明,该方法具有较强的非静态和非线性信号处理能力,并能在小样本情况下取得出色的行星轮轴承剩余寿命预测效果。
In order to address the problem about the remaining useful life(RUL)prediction of planet bearings under small samples and varying operating conditions,a RUL prediction method of planet bearings based on conditional deep recurrent generative adversarial network(C-DRGAN)and action discovery(AD)is presented.The gated recurrent unit neural network is integrated with conditional generative adversarial network to construct the C-DRGAN,which extracts the fault features from the nonlinear and non-stationary signals so as to realize the RUL prediction of planet bearings under small samples and varying operating conditions conditions.Then the training algorithm based on AD is employed to train the C-DRGAN to enhance the convergence speed and reduce the training time.Finally,according to the C-DRGAN after training,a multiple linear regression classifier is employed to predict the RUL of planet bearings in test samples.The effectiveness of the proposed method is validated through an accelerated fatigue life experiment of planet bearings.The results show that the proposed method processes strong processing adaptability to the nonlinear and non-stationary signals and obtains the excellent performance in the case of small samples.
