technical field [0001] The invention relates to the technical field of hydraulic manifold design; in particular, it relates to a flow channel design method for a high-energy-efficiency hydraulic manifold, which is used to reduce the loss along the flow path and the local loss and improve the energy efficiency of the hydraulic manifold. Background technique [0002] Hydraulic transmission technology has the advantages of high power, small size and stable transmission, and is widely used in aerospace, forming equipment and construction machinery and other fields. The hydraulic manifold has become an important component in hydraulic transmission due to its compact structure, convenient installation, easy maintenance, low leakage and low vibration and noise. However, due to the fact that traditional hydraulic manifolds use mechanical cross-drilling to manufacture internal flow channels, the problems of process hole volume, sudden change of flow channel cross-section, and space u...

AI Technical Summary

Problems solved by technology

However, limited by the mechanical cross-drilling method of the traditional hydraulic manifold to manufacture the internal flow channel, the problems of the process hole cavity, the sudden change of the flow channel cross-section, and the space utilization rate are obvious, resulting in excessive loss along the process and local loss, resulting in hydraulic pressure. Manifold energy inefficiency

[0003] In addition, in the traditional design process, the layout of hydraulic components and the connection of flow channels between ports are manually performed. The low degree of automation leads to insufficient flexibility and low efficiency of the design, and it is impossible to achieve rapid iterative optimization.
