学　术

　　由机械与电气工程学院主办的学术报告本次邀请印度理工学院德里分校Ashish Kamalakar Darpe教授来校交流，将为师生带来三场学术报告。第一场学术报告的具体安排如下，欢迎感兴趣的师生参加。

　　一、主　题：Fault Classification in rolling element bearings

　　二、主讲人：印度理工学院德里分校　Ashish Kamalakar Darpe　教授

　　三、时　间：2018年6月25日（周一）14:30-16:00　　

　　四、地　点：清水河校区主楼C1-213

　　五、内容简介：

　　The rolling element bearings may prematurely fail due to several reasons including harsh operating conditions, dust/dirt ingress in raceway areas, improper mounting conditions. This talk will explore how a damaged inner or outer race of the bearing manifests itself in the changed vibration behavior of the bearing. Using simulations accounting for the various dynamic effects, bearing fault identification and classification is attempted based on instantaneous energy and autocorrelation. The results are validated through experimental measurements and analysis. The coefficient of variation and Chi-square test statistic allows defect classification in the bearings.
