| 摘 要： | 为了提高涡轮叶片的设计效率,在分析已有涡轮叶片截面线参数化造型技术优缺点的基础上,基于B样条曲线实现了涡轮叶片截面线的参数化造型和参数化修改,并编写了叶片造型程序,实现了叶片流场模型的自动化生成.以某型号涡轮叶片为例,对其进行三维流场数值模拟,然后采用遗传算法和序列二次规划法算法的组合,以涡轮的气动效率为目标函数,对涡轮叶片进行了气动优化.算例结果表明文中所建立的涡轮叶片自动优化设计体系是可行的.

| Abstract: | To improve the design efficiency of turbine blade, based on analyzing the advantages and disadvantages of the existing parameterized modeling of the turbine blade section curve, the paper actualized the parameterized modeling and parameterized modification of the section curve. The blade modeling was programmed and the flow flied calculation of blades was automatically modeled.3D flow flied of blades was simulated, then aerodynamic optimization was carried out using the GA and SQA algorithms by taking the a... |
