Optimized Design of Visualization of Blades and Forecast of Performance Based on Genetic Algorithm

该文采用面向对象的编程技术,通过调用OpenGL函数,用VC++语言编制了液力变矩器工作轮循环圆和叶片的交互式集成可视化设计程序,构建了叶片形状设计的数学模型及性能评价模型。基于遗传算法进行了以最高效率和高效区范围为优化目标的叶栅系统优化计算和分析,绘制性能曲线,并利用Ansys-CFX软件,对优化前后的结果进行了三维流场分析。通过实例验证表明,优化设计的结果是合理的。

A kind of new design method of torque converter 3D blades is done by VC＋＋ and OpenGL Convenient interaction,visualization and real-time rendering are three important considerations in programming. The model of blades figure and forecast of performance can be built. The optimum design model is established by object function which is based on the maximum efficiency and area of high efficiency. The analysis of the design result is done by Ansys-CFX. An example proves that the method of optimized design is feasible.
