| 摘 要： | 采用基于梯度的优化方法来研究气动外形优化设计问题,其梯度的计算是通过求解伴随方程得到,与传统的差分法和遗传算法相比计算量大大减小.采用一种全新的隐式约束处理方法:约束自动地满足而且设计状态不改变,因而程序设计也相对简单高效.给出的算例也达到了预期的优化设计目标.

| Abstract: | The optimization problem of aerodynamic shape design is studied using a gradient-based optimization method,in which the gradient is calculated through solving an adjoint equation.Compared with the conventional difference method and the genetic method,the computational cost of the new method is greatly reduced.A completely new method to deal with implicit constraints is also introduced,where constraints are satisfied automatically but the design conditions are not changed so that the programming is comparati... |
