摘要

为了解决船型优化中仿真计算复杂耗时的问题,基于自适应采样的近似模型技术的应用日益广泛.基于Kriging近似模型和留一法误差,发展了一种基于均匀设计的最大熵自适应采样方法.通过与基于增量拉丁超立方方法进行对比,所提方法得到的自适应样本分布更加均匀,并且其全局近似模型精度更高.将所提方法应用于S60的船型优化中,很好地验证了该方法的有效性.

Abstract

In order to handle the problem of complex and time-consuming simulation calculation in hull form optimization, the approximate model based on adaptive sampling has been widely used. In this paper, a maximum entropy (ME) adaptive sampling method based on uniform design (UD) is developed based on the Kriging approximate model and the leave-one-out (LOO) error method. Compared with the incremental Latin hypercube design (LHD) method, the adaptive sample distribution obtained by the proposed method are more uniform, and the accuracy of the global approximation model is higher. The proposed method is applied to the S60 hull form optimization, and the effectiveness is verified.

Key words： hull form optimization; adaptive sampling; uniform design (UD); maximum entropy (ME) sampling
