Abstract:
Based on the theoretical derivation, the basic formula of the dynamic response of sub-modelling method was obtained based on structural dynamic stiffness under complex cutti4ng boundary conditions. Firstly, a sub-modelling method was studied by using 2 sub-models of shell-shell and shell-solid as a research object based on a simply supported plate. The accuracy and the high efficiency in the 2 sub-models were researched. Then, the good applicability of dynamic sub-modelling method on the complex structure was proved by using a satellite model as a research object. The results show that the computational efficiency is improved with the sub-modelling method under a premise of local computation precision. The high precision can be achieved with only 1 layer and 3 layers of boundary nodes when using shell-shell and shell-body sub-modelling methods, respectively. Fine results can also be obtained under the condition of a sharp incompatibility between the whole model and the sub-model on complex structures.
