Dynamic optimization of the turbine engine frame foundation based on kriging model

This paper is based on Kriging method to optimize the dynamic response of turbine engine frame foundation,Ansys software is used to build the model and to analyze the response of turbine engine frame foundation.In order to solve this problem,the multi-objective method of optimization is used;the section area and geometrical position are regarded as design variables.The objectives of this model are to minimize the weight of the structure and the maximum dynamic displacement.In this paper,section area of optimization is interchanged with geometric position of optimization,the result shows that: this method has good applicability.The results show that this method of optimization is relatively effective;it has a certain value in the field of engineering.
