| 摘 要： | 文章对约束物体零攻角高速出水的轴向水动力参数进行了辨识,获得了轴向方向的附加质量和阻力系数的非线性模型.同时,用零攻角的其它斜出水试验状态下的试验数据对辨识结果进行了验证,验证表明,利用辨识获得的水动力模型计算的结果与试验数据比较吻合,辨识算法是有效的,获得的水动力模型是可靠的.

| Abstract: | A method of parameter identification,based on the artificial intelligence technique,for hydrodynamic forces acting on an axis-symmetric body exiting water obliquely is investigated in this paper.The model of axial added mass coefficient and of the velocity-related axial force coefficient are successfully obtained by this method.Using this model to identify the hydrodynamic parameters for other test case shows that the results calculated from the identified parameters agree quite well with the original test results.It is also shown that the identification method is effective and the model of axial unsteady hydrodynamic forces during water exit is reliable. |
