摘要
为满足高速列车转向架轴承状态监测的教学需要,考虑高速列车实际服役工况,根据驱动、激振、控制的相关理论,研制了适合高速列车轴箱、齿轮箱及电机等多类轴承的轴承系统实验台;同时研发了多场耦合监测系统,使轴承运行状态监测由单点监测发展为场监测;实验证明,多场信息融合能提升轴承故障诊断的有效性,对探索轴承多维故障特征以及提升学生的理论创新能力有极大的帮助。
In order to meet the teaching needs of high-speed train bogie bearing condition monitoring, considering the actual service conditions of high-speed train, and according to the relevant theories of drive, excitation and control, a bearing system test-bed suitable for high-speed train axle box, gearbox and motor is developed. At the same time, a multi field coupling monitoring system is developed, so that the bearing operation condition monitoring is developed from single point monitoring to field monitoring. The experiment shows that multi field information fusion can improve the effectiveness of bearing fault diagnosis, and is of great help to explore the multi-dimensional fault characteristics of bearings and improve the theoretical innovation ability of students.
