| 摘 要： | 针对7500吨浮吊齿轮箱故障诊断问题,将离散小波变换和Tikhonov支持向量机结合建立了一个浮吊齿轮箱故障诊断系统。在输入层对振动信号进行离散小波变换,提取不同频带的能量参数作为故障特征向量,利用这些特征向量进行Tikhonov支持向量机的学习,训练后的Tikhonov支持向量机诊断浮吊齿轮箱故障。实验结果表明,离散小波Tikhonov支持向量机具有很强的故障识别性能和鲁棒性,诊断精度优于常规的BP网络方法。

| Abstract: | Discrete wavelet Tikhonov support vector machines(SVM) is presented to solve the problem of fault diagnosis for 7500 ton floating crane gear box,which combines discrete wavelet transform and Tikhonov support vector machines.Vibration signal is processed by discrete wavelet transform at the input layer and the detail energy parameters are obtained as fault character vectors.Tikhonov support vector machines is trained according to these character vectors.The trained Tikhonov support vector machines diagnoses ... |
