| 摘要: |
| 为减少叶片设计参数，提高设计效率，用儒科夫斯基型线进行液力变矩器导轮叶片造型研究.对儒氏型线进行简化，并采用尾部加厚处理，使其适应液力变矩器流动要求；构建儒科夫斯基导轮叶片型线模型，用该模型对一系列液力变矩器导轮叶片进行拟合.仿真计算与实验结果对比表明：处理后的儒氏型线能够精确表达已有液力变矩器导轮叶片，可以用于液力变矩器导轮叶片的设计.在集成式液力变矩器设计平台上，利用基于存档的小种群遗传算法对儒氏型线液力变矩器导轮叶片进行优化，结果显示：与传统叶片造型方法相比，儒氏型线可以利用较少的参数有效地进行液力变矩器导轮优化设计，缩短了设计周期.

| Abstract: |
| In order to reduce design parameters and shorten design cycle, Joukowksky profile was utilized to construct torque converter stator blade. By simplifying the Joukowksky equation and adding a thickness term to its end, the Joukowksky stator blade model was given. According to fitting results, Joukowksky is able to present the existing stator blades and hence is suitable for stator blade design. Afterwards, the archive-based micro genetic algorithm was employed to optimize the Joukowksky stator blade based on an integrated 3D blade design system. The results indicated that the Joukowksky profile could be used in stator blade design with less parameters and the performances were improved after the optimization.
