摘要
为了获得更为精确合理的近似模型,在多项式响应面、RBF径向基函数和Kriging三种单一近似模型的基础上构建组合近似模型以实现响应拟合,并以数值函数为例验证组合近似模型的准确性与适用性。以海洋平台支持船的总阻力为研究对象,采用多种试验分析方法进行取样,根据样本点及阻力响应值完成了组合近似模型的构建,并与模型试验及其单一近似模型进行对比分析。研究结果表明,与单一近似模型相比,组合近似模型所得的阻力响应值更接近模型试验结果,能够有效提高计算精度与设计效率,在海洋平台支持船的初步设计中具有较大的应用价值。
In order to obtain more accurate and reasonable surrogate model, the combined metamodel is constructed and applied to fit response based on the RSM, RBF and Kriging, and the numerical function is taken as an example to validate the accuracy and applicability of the combined metamodel. Taking the offshore supply vessels as the research object, using a variety of analysis and Design of Experiments method of sampling, the combined metamodel for ship total resistance is constructed and compared with the model test and other single surrogate models. The results show that the resistance responses of combined metamodel are closer to the model results comparing with other single surrogate models. The use of combined metamodel can effectively improve the calculation accuracy and design efficiency and has great application value in the preliminary design stage of offshore supply vessels.
