About Journal Experts Special
Chinese Hydraulics & Pneumatics, founded in 1977 with support from Beijing Research Institute of Automation for Machinery Industry, is a scientific journal that is intended to communicate information and reflect trends referring to hydraulics and pneumatics. Its publications cover both basic and applied research focusing on new technology, new design, new equipment and new material, and also introduce the industrial information on products and enterprises. Engineering technicians are the primary audience for the journal, which is also widely popular with business managers and marketing staffs as well as teachers and students in universities and colleges.Chinese Hydraulics & Pneumatics publishes in China as well as abroad.

Lightweight Design and Manufacturing of Complex Hydraulic Passageway Based on Additive Manufacturing
ZHANG Lei, ZHU Yi, YANG Hua-yong
Selective Laser Melting (SLM), as one type of additive manufacturing technology, uses a laser to selectively melt metal powders in a layer-by-layer manner. The technique is able to process very complex structures and lightweight parts. On the basis of conventional manufacturing process, hydraulic passageways are suffered from excessive pressure loss, high weight, and large size. We design a servo valve manifold block with weight reduction of 37% based on the SLM technology. The simulation results show that pressure loss is reduced by 50%. Finally, we propose a SLM-based lightweight design of complex hydraulic passageways based on constraint analysis, model design, and simulation. The research shows the potential of applying additive manufacturing to manufacture hydraulic manifold blocks, which can achieve lightweight and improve flow characteristics.
