Hydraulic coupling of CAD and its dynamic characteristics

Context for forklift hydraulic coupling for detailed research and analysis. The use of Pro / E modeling software and CFD flow field analysis software hydraulic coupling internal flow field numerical calculation, and the results were analyzed in detail. Get the fluid coupling output torque at rated conditions, and with the manufacturers should be provided for during the actual results were analyzed. Finally, the C programming language will be rated condition data expanded to the entire operating range. This specific study mainly the following aspects: (1) the use of Pro / E software, by simplifying assumptions, with the parameterization of the parts for  Hydraulic tube fittings  coupling modeling, assembly, and conduct interference analysis. (2) extracting section flow channel entities, binding studies that, according to theoretical calculations, the gambit meshing software, quality inspection, to determine the boundary conditions and the region. (3) the meshed model into fluent software for numerical simulation, the use of selected models and algorithms for filling rates were 80% and 30% of the two conditions is simulated, and according to the results of numerical simulation filling rate under different hydraulic coupling internal velocity field, the pressure difference, liquid, etc. comparative analysis and torque detected and compared with the experimental data,
