| Abstract: | Based on the concept of dynamic sub-structures, the synthesis method in step-by-step is put forward. The band width of mass matrix can be improved, and storages and calculating time can be reduced, large structure analysis can be made on a micro-computer. The free vibration character of a shallow draft ship is successfully calculated. The results show that the theory and method described in this paper are of important practical value. |
