| Abstract: | To design the low cost and energy conserving hydraulic power mechanism is one of the key point to expand the applica -tion of electro-hydraulic servo system in civilian areas .The power mechanism of shock absorber testing table was designed and calculat -ed based on the discussion of the load matching rules , the servo-valve and hydraulic cylinder were determined .Meanwhile, the flow of the hydraulic power units and the working volume of the accumulator were analyzed and derived according to the parameters of shock absorber .The results show that the shock absorber testing table possess proper steady-state behavior and dynamic performance with 30 Hz frequency bandwidth , and then the rationality of mentioned electro-hydraulic servo system project concept demonstration process is verified. |
