| Abstract | TN911.72; 针对传统方法构建的健康因子各类性能指标不高、信息冗余的问题,提出一种基于改进受限玻尔兹曼机(restricted Boltzmann machine,RBM)的滚动轴承健康因子构建方法.首先,提取滚动轴承振动监测信号时域、频域特征组成物理健康因子集.其次,将RBM隐藏层节点数随时间变化斜率引入到正则化项中,提取物理健康因子集中的趋势性特征.最后,利用滚动轴承全寿命周期试验验证所提方法的有效性.实验结果表明,相对于主成分分析(principal component analysis,PCA)法、传统RBM虚拟健康因子构建方法,基于改进RBM构建的虚拟健康因子单调性分别提高178.0％和33.3％,趋势性分别提高126.8％和16％,鲁棒性分别提高60％和6.02％. |
