| Abstract: |
| High computing resource is needed to analyze the dynamic response of structures if train-tunnel dynamic interaction is considered and refined three dimensional structure models are used.In this paper,a train-structure interaction balanced algorithm for domain decomposition is designed and implemented according to the characteristics of train-structure dynamic coupling model.Employing three dimensional dynamic finite element models,two examples of the train-structure coupling system are analyzed using this partition algorithm.The results show that this method has better parallel performance than the Recursive Coordinate Bisection method. |
