基于Kriging模型的船舶主机隔离系统抗冲击优化
Antiimpact optimization of the isolation system of a marine engine based on the Kriging model
摘要
Abstract
The impact response analysis of the isolation system of marine engines based on the traditional finite ele-ment model is complicated and requires multiple calculations.To improve the impact resistance and optimization ef-ficiency of the system,this study takes seven parameters,such as stiffness and damping of the limit isolation sys-tem,as the design variables and the relative displacement response and maximum peak value of the absolute accel-eration response of the impact response of the isolation system as the response values.The Kriging surrogate model was established,and multiobjective optimization was conducted using the Kriging surrogate model constructed by NSGA-II.The optimization objective was the minimum sum of the relative displacement response and the maximum peak value of the absolute acceleration response.Compared with the initial scheme,the relative displacement re-sponse is reduced by 27.139%,and the absolute acceleration response is reduced by 37.846%.The complementa-ry results showed that the established surrogate model can accurately predict the impact response of the isolation system.After optimization,the impact resistance of the isolation system is significantly improved.关键词
