| 摘 要： | 提出一种无网格模型的子结构分析方法。基于界带分析方法,处理无网格模型子结构之间的连接,能够保证各个子结构之间无缝连接,从而使无网格子结构模型与原无网格模型等价,同时还能够降低无网格刚度方程的计算规模。数值算例表明,本文方法是正确可靠的,可以保证各个子结构之间无缝连接。

| Abstract: | A method on sub-structure analysis for mesh-free model is developed.The Inter-Belt analysis theory is employed to accurately deal with the connection between sub-structures,which leads to the same result for both mesh-free sub-structure model and primary mesh-free model.Moreover,the presented method can reduce the scale of stiffness equations.The numerical results show that the presented method is correct and reliable,and can realize the seamless connection between two sub-structures. |
