摘要

PPROBLEM TO BE SOLVED: To provide an object shape optimizing method or the like performed for providing a desired aerodynamic characteristic to an object by using aerodynamic parameters (dynamic lift, aerodynamic sound or the like) determined experimentally. PSOLUTION: In the object shape optimizing method for providing the desired aerodynamic characteristic to the object in fluid, a model that simulates the cross-sectional shape of the object and whose profile is variable is used. First, a constraint condition is set in S1, and an initial profile of the cross-sectional shape of the object under the constraint condition is set and the profile of the model is set so as to correspond to the initial profile in S2. The model is placed in the fluid and physical quantity relevant to an action received from the fluid by the model is measured in S3, and an objective function is calculated using the measured value in S4. Until the objective function becomes minimum or maximum in S5, the profile of the cross-sectional shape of the object is changed by the optimizing method (S6), and the profile of the model is changed so as to correspond to the changed profile (S7).

解决方案：在用于为流体中的物体提供所需空气动力学特性的物体形状优化方法中，使用了模拟物体横截面形状且轮廓可变的模型。首先，在S1中设置约束条件，并且在约束条件下设置对象的横截面形状的初始轮廓，并且设置模型的轮廓以与S2中的初始轮廓相对应。将模型放置在流体中，并在S3中测量与从模型接收到的流体相关的动作相关的物理量，并在S4中使用测量值计算目标函数。在S5中直到目标函数变为最小或最大之前，通过优化方法改变对象的横截面形状的轮廓（S6），并且改变模型的轮廓以对应于改变后的轮廓（S7））。
