Reliability Analysis on the Chassis Hydraulic System in Hydraulic Loader

Abstract:

Hydraulic loader is a major equipment for the airport engineering, the high efficient excavation is closely related to the reliability of equipment. Due to severe environment in the construction site, the chassis hydraulic system has high failure rate in the loader. Based on the criticality matrix analysis, some fatal failure modes were traced, including the leakage of motor, the pollution of hydraulic oil, the suction air of pump. Through the reliability prediction analysis, the estimated reliability of the chassis hydraulic system is 0.27, and mean time between failures of the system is 183h, in addition, critical components in the system are also determined. The above result could be used as reference for the optimization designing.
