Fault Analysis and Diagnosis of Downhole Traction Robot Hydraulic System

Fault diagnosis of downhole traction robot has characteristics special mechanical structure, complicated working condition and lack research data. In this paper, a method fault analysis tractor hydraulic system based on model is presented. The failure mode mechanism key components in telescopic are analyzed. proposed the mathematical component. Based AMESim, established, single multi-fault simulated, which can collect data specific process. To carry forward engineering application, simulated internal leakage cylinder set up schemes carried out, prove that consistent with theoretical simulation. not only lays basis for detection, but also provides guidance construction implementation diagnostic system.
