翻车机液压在线故障诊断专家系统设计

Design of on-line fault diagnosis expert system for hydraulic system of car dumper

设计了一种翻车机液压在线监测及故障诊断专家系统,利用仿真软件AMESim进行液压系统仿真分析建模,建立翻车机液压系统参数在线监测系统,对采集的信号进行处理和分析,提取能够作为故障诊断的特征信息,参考故障仿真结果及故障诊断维修经验建立故障诊断专家系统,为现场故障诊断提供了支持。

The paper proposes an on-line monitoring and fault diagnosis expert system for the hydraulic system of car dumpers. Simulation software AMESim is used for simulation analysis and modeling of hydraulic systems and es- tablishing an on-line parameter monitoring system for the hydraulic system of car dumpers, which can process and ana- lyze the collected signals and extract feature information for fault diagnosis. Fault diagnosis expert system is established based on fault simulation results and experience in fault diagnosis and maintenance, which provides support for on-site fault diagnosis.
