:In order to provide 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 mechanical hydraulic system based on optimized fault tree analysis model is proposed. Consider the composition and structure of the mechanical hydraulic system, simulate the operation process of the mechanical hydraulic system, and set up in-situ testing points for the mechanical hydraulic system. Collect the system operation data at the measuring points, use the optimized fault tree analysis to judge whether the current mechanical hydraulic system is in fault status, calculate the flow, hydraulic leakage and other parameters for the mechanical hydraulic system in fault status, and obtain the in-situ inspection results of the mechanical hydraulic system. Through performance testing experiments, it is concluded that compared with traditional detection methods, the optimized design method has reduced parameter detection errors in hydraulic value, hydraulic oil flow rate, and leakage rate by 4.3N/m, 0.41L/min, and 0.36mL, respectively, and the detection process has a lower degree of damage to the system. This proves that the optimized design method has higher detection performance.
