摘要：To design hydraulic manifold block (HMB) with high through-flow quality, calculated fluid dynamic (CFD) method is utilized to study the flow characteristics for internal channel. The study results show that the layout and connection relationship of the channel has great influence on the performance of HMB. In the layout way which has a similar structure of channel connectivity, priority should be given to the same surface or neighborhood surfaces. To improve the quality of channel flow, according to the relationship of craft pore structure and pressure drop, the optimal design direction is put forward, which includes reducing the length of craft pore, increasing the craft pore diameter and so on. And then, by calculating the local resistance coefficient with low Reynolds number on the performance of right-angle turn, the design of right-angle turn is optimized. HMB structural optimization design strategy is established from a performance point, which makes foundation for the overall optimization design of HMB combined with performance constraints and structural constraints.
