基于混合方法的随机板-梁结构动力响应特性数值研究
Numerical research on the dynamic response of plate-beam structure with randomicity based on the hybrid method
摘要
Abstract
In the present work the basic theory of hybrid finite element-statistical energy analysis (FE-SEA) method was first described, and the FE model of the plate-beam structure with randomicity was considered. Then the ensemble average dynamic response results of FE model was calculate based on the Monte Carlo Finite element method. Tthe hybrid FE-SEA model of structure is built up and the subsystem dynamic response of hybrid model is calculated. Finally, we compare the dynamic response results obtained by the two different methods. The result shows that the hybrid FE-SEA method can reduce the excessive demands of FE method for a large number of DOFs. In addition, this method can reduce the model size and the amount of computation, which provide an accurate and efficient practical application with randomicity.关键词
