摘　　要：为了对液力减速器叶片前倾角度进行参数优化,建立了液力减速器叶栅参数三维集成优化仿真平台。以叶片倾角为设计变量,三维CFD分析作为求解器进行试验设计,并根据试验样本结果构建响应面法模型(RSM)进行优化,得到一套最优的动、定轮叶片倾角参数。就叶片倾角参数对液力减速器内流场特性、制动外特性的影响进行了分析,并结合试验数据对优化前后制动性能进行了对比。结果表明,优化仿真平台精度较高,结果可信。优化后的液力减速器制动性能显著提高。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.
