Study on the Strategies for Dealing with Interface Conditions among Substructures in the Substructure Synthesis Method
Strategies for combining reduction and non-reduction substructures in the system structure are presented and investigated. A cylindrical shell structure whose length and diameter are 4.2m and 0.4m, respectively, is designed. It consists of 5 parts and there is a shaft passing through the fourth and the fifth parts. To investigate the vibration response of the shell by the substructure synthesis method, the shell is divided into 3 substructures and joints between them are modeled as bolt connections. Application of the proposed strategies in the substructure synthesis method for predicting vibration response of the cylindrical shell structure is discussed. Comparison between the vibration response predictions and the experimental. results shows that the proposed method is valid. By conclusions, impact of the interface conditions on the vibration response predictions is much obvious, and reasonable prediction results can be obtained by applying the proposed strategy.
