A Superelement Simplified Analysis for the Vibration Systems of the Complex Structures

Chen Guoping Zhu Demao (Research Institute of Vibration Engineering)  
In this paper, a superelement analysis method based on the common finite element modeling is developed to reduce the Degrees of Freedom (DOF) for the vibration systems of the large complex structures. A simplified dynamic reduction is used in the internal domains of the superelements, and a locai displacement field reassumption is introduced on the boundary areas. This method greatly reduces the order of DOF. expands the ability of solution, and is simple to program and convenient to calculate. A reduction criterion of internal DOF is suggested through the perturbation analysis. Some numerical examples verify that the method is very effective and has high calculation precision.
