| 摘 要： | 基于Kriging模型和最优对称拉丁超立方体抽样方法，以简化的水下潜艇结构模型为例建立水下相对复杂结构振动声辐射计算的代理模型，可对水下潜艇结构模型进行共振频率和声功率级的预测。建立的代理模型可以在整个设计变量尺寸范围内对模型的振动声辐射进行实时预测。由计算结果得出，使用基于Kriging方法的代理模型能较准确地完成固有频率和声功率级的预测。所建立的代理模型能快速、准确地预报在整个设计变量尺寸范围内潜艇结构模型的振动声辐射。

| Abstract: | In this paper, a surrogate model based on the Kriging model and the optimal symmetric latin hy- percube sampling method is established to calculate the resonant frequency and the corresponding power level of acoustic radiation for underwater submarine structures. Particularly, this model can achieve re- al-time estimation of the vibro-acoustic response in the whole design space. It is observed that the Kriging model provides estimation results with high accuracy, and the overall surrogate model is applicable for the rapid prediction of submarine shell vibration and acoustic radiation. |
