Abstract: To optimize the blade forward-curved angle of the hydraulic retarder, a 3-D integrated optimization simulation platform was built. Taking the blade angle as the design variable, the design of experiment was performed using the CFD analysis as the solver, and a response surface method model was built according to the test sample results, the optimization was accomplished. A set of the optimized blade curved angle parameters of the rotor and stator wheels were obtained. The effects of the blade angle parameters on the internal flow characteristics and the brake performances were analyzed, and the brake performances before and after the optimization were compared using the test data. The results showed that the brake performances of the hydraulic retarder with optimal blade angle parameters were improved obviously. The built 3-D integrated optimization platform is accurate and reliable.

Key words: turn and control of fluid, hydraulic retarder, 3-D integrated optimization, design of experiment, response surface method
