In-situ Detection of Mechanical Hydraulic System Based on Optimized Fault Tree Analysis Model
In order to provide an effective data reference for the maintenance of mechanical hydraulic system without destroying the existing internal structure of the system,an in situ detection method of the mechanical hydraulic system based on optimized fault tree model was proposed.The composition and structure of the mechanical hydraulic system are considered to simulate the operation process of the mechanical hydraulic system,and set up the in-situ detection of the mechanical hydraulic system.The operating data of the system is collected at the measuring location,and the constructed optimization fault tree is used to determine whether the current mechanical hydraulic system is in fault state.The flow rate,hydraulic leakage and other parameters are calculated for the mechanical hydraulic system in fault states,which obtains the in-situ detection results of the mechanical hydraulic system.Through the perform-ance test experiment,the results show that compared with the traditional detection methods,the optimized method reduces the detec-tion errors of hydraulic value,hydraulic oil flow and leakage respectively,with different degrees reduced,and the poor effects on the system detection process are lower,which indicates that the optimized design method has a higher detection performance.
