摘要：
Additive manufacturing(AM) technology is applied for the high integrated and lightweight hydraulic system because of its ability to form complicated structure. However, the surface roughness of flow channel formed by AM is different from traditional drilling and casting ones, especially in complicated pipeline system. It is urgent to study the pressure loss mathematic model of flow channel formed by AM because the classical pressure loss mathematic model can not be used directly. Y-shaped flow channel, a typical flow channel, is taken as the research object. The pressure loss mathematic model of Y-shaped flow channel is established based on Bernoulli equation, Momentum theorem, and Darcy formula. The influence of AM forming Angle on the surface roughness is analyzed. The influence laws on the splitting ratio, branch Angle, and flow channel diameter of pressure loss are studied by simulation. The Y-shaped flow channel test platform is built and the models of Y-shaped flow channel are manufactured by AM. Then the pressure loss of the flow channels under different splitting ratio, branch Angle and flow channel diameter is measured. The results show that the average error of pressure loss between simulation and calculation is less than 9% and the one between experiment and calculation is less than 8%. Research can lay a foundation for the design of low pressure loss pipeline formed by AM. © 2021 Journal of Mechanical Engineering.
