The efficiency-reinforcement design framework of hydraulic reciprocating sealing driven by ideal solution is proposed. The seals' main operating characteristics, seal efficiency control, leakage control and friction losses control are analyzed. The efficiency-reinforcement sealing element is designed according to TRIZ ideal final result searching strategy, sealing mechanism and tribological behavior. The computational model of efficiency-reinforcement sealing element is established with ANSYS, and its stress, strain and contact pressure distribution in different fluid pressure are also analyzed. The results demonstrated that the presented seal element outperforms the old seal in efficiency reinforcement capacity.
