Adaptive co-simulation method and platform application of drive mechanism based on Fruit Fly Optimization Algorithm

Abstract

The simulation of the control rod drive mechanism is a co-simulation process of multi-physics coupling. It has the problem of conflict between simulation accuracy and efficiency in the simulation process based on the centralized simulation idea. Therefore, a multidisciplinary co-simulation method and simulation platform with adaptive step size are proposed in this paper. According to the characteristics of the simulation nodes, the fruit fly optimization method is used to determine the adaptive step size of different simulation stages. A multi-disciplinary co-simulation platform is constructed based on the Isight which can integrate co-simulation tool. The co-simulation process of the control rod drive mechanism is completed with the method and platform. The results show that the simulation accuracy of the platform built in this paper is increased by 23%, and the simulation efficiency is increased by 64%, which verifies that the proposed method has good compatibility in terms of simulation accuracy and efficiency.
