Due to the lack of reliable big data, data-driven methods cannot be used to study the life distribution of hydraulic components. Facing the leakage failure of the hydraulic component is caused by the failure of the O-ring wear in hydraulic contact seal, According to the O-ring adhesive wear principle and Archard model, a method of fusing the internal leakage life test of hydraulic components with the simulation experiment based on the equivalent cross-sectional diameter of the O-ring is proposed. The leakage life test and simulation scheme of hydraulic cylinder designed by this method are used to solve the life distribution of piston hydraulic seal O-ring based on covariate. Finally, the life distribution response surface is established. It is proved that the method is feasible. The method provides a data channel for studying the reliability related problems of hydraulic components.
