摘要/Abstract

摘要： 为对双循环圆液力缓速器弯叶片叶形参数进行优化设计，搭建叶栅系统优化设计平台。建立缓速器内流道参数化模型，并通过网格独立性研究对仿真模型可信度进行验证。基于三维流场仿真技术，以叶形包角与工作面内外圆弧半径为设计变量，进行试验设计研究，分析设计参数对缓速器制动性能的影响，构建近似模型，采用多岛遗传算法进行全局优化设计，得到最优的设计参数，并对优化前后缓速器内流场特性与制动性能进行对比分析。分析结果表明：优化后缓速器的制动性能显著提高，制动力矩平均增幅可达42.3%.

Abstract: An optimization platform of hydraulic retarder cascade is established to optimize the parameters of the bowed blade of dual torus hydraulic retarder. The parametric modeling of single periodic flow is achieved, and the grid independence is studied to validate the credibility of simulation model. Based on CFD simulation, the design of experiments is adopted to study the influences of blade wrap angles and pressure surface radii on the brake performance. The response surface methodology is built to get the optimum parameters, and the multi-island genetic algorithm is used for global optimization design. Comparison of internal flow field and brake performance before and after optimization shows that the brake performance of hydraulic retarder with the optimum parameters is improved observably, and the braking torque is averagely increased by 42.3%.

Key words: fluid drive and control, dual torus hydraulic retarder, bowed blade, blade design, optimization design
