本文旨在利用代理模型技术实现高强聚乙烯-负泊松比效应复合结构抗侵彻性能的快速预报，首先对高强聚乙烯层合板抗弹片侵彻数值仿真方法进行验证，建立可靠的高强聚乙烯-负泊松比效应复合结构抗侵彻数值仿真模型，并构建了其弹道极限快速预报的代理模型；分析了不同的代理模型方法和采样方式对代理模型精度的影响规律。结果表明，相较多项式响应面和径向基函数代理模型，Kriging代理模型的预报精度最高，最大相对误差为18.1%，归一化均方根误差为8.8%，相关系数为0.85；正交设计试验方法较拉丁超立方采样方式更适合复合结构弹道极限速度预报，本文为侵彻载荷下结构动态响应快速预报研究提供了参考。
The purpose of this paper is to explore the application of surrogate model on the penetration resistance of ultra-high molecular weight polyethylene - negative poisson's ratio structure composite sandwich panels, and achieve accurate and reliable rapid prediction of dynamic response of composite structure. Firstly, the numerical simulation method of penetration resistance of ultra-high molecular weight polyethylene laminated plate was verified, and a reliable numerical model of penetration resistance of ultra-high molecular weight polyethylene - negative poisson's ratio structure composite sandwich panels and a surrogate model for rapid prediction of ballistic limit velocity of composite structure were established. Then, the applicability of different surrogate models and sampling plans to the object of this paper is discussed. The results show that compared with the polynomial response surface model and the radial basis function model, the Kriging model has the highest prediction accuracy. The maximum relative error is 18.1%, the normalized root mean square error is 8.8%, and the correlation coefficient is 0.85. The orthogonal design method is more suitable for ballistic limit velocity prediction of composite structures than latin hypercube sampling method. The work in this paper provides a reference for the rapid prediction of structure dynamic response under penetration load.
