摘要
在传统的威布尔可靠性分析基础上,提出了基于支持向量机的威布尔可靠性分析方法,采用编程的方式绘制了威布尔概率纸,通过程序化的方式分析估计威布尔概率参数,进行可靠性寿命分析,并对比分析了基于支持向量机和传统的威布尔可靠性分析的效果。实例分析结果显示,在威布尔可靠性分析中,支持向量机的拟合精度较好,可作为威布尔可靠性分析的一种新方法,特别适用于小样本的情况。
Based on the traditional method of Weibull reliability analysis, a new Weibull reliability analysis method based on the support vector machine （SVM） is proposed in this paper. The Weibull probability paper is programmed, by which the parameters of Weibull distribution and reliability life analysis are estimated. And the effectiveness of new Weibull reliability analysis based on SVM and the traditional one are compared. The simulation experiment results show that the new method based on SVM can improve the analysis precision and effectiveness. So the reliability analysis based on SVM can be regarded as another choice of Weibull reliability analysis, which is especially suitable for the small samples.
