文章介绍了一种基于粒子群优化算法的整星有限元模型修正方法,首先对整星进行了有限元建模和模态分析,并将试验和分析结果进行了相关性分析,然后引入粒子群优化算法对整星有限元模型进行修正,提高了模型分析和预示精度,为整星级有限元模型修正提供了一种新的手段。 In this paper, a modified method based on Particle Swarm Optimization (PSO) for the whole-star finite element model is introduced. First, the finite element modeling and modal analysis of the whole star are carried out. The correlation analysis between the test results and the analysis results is carried out. Then the particle swarm The optimization algorithm modifies the finite element model of the whole star, which improves the accuracy of model analysis and prediction and provides a new method for the rectification of the full-scale finite element model.
