ABSTRACT:
Methods for performing a dynamic analysis of complex systems are described. The dynamic analysis of complex systems is performed by sub-structuring of the system into a plurality of sub-structures. The sub-structures and the interfaces between the sub-structures are modelled using a generalized eigenvector analysis of a discretized model of a full system or a subassembly thereof comprising at least two sub-structures. The sub-structures then are combined at the interfaces into a combined system. The combined system then is solved. Optionally, selected sub-structures may be reduced. Performing such a dynamic analysis allows studying characteristics such as e.g. vibration and/or acoustical effects in a computational efficient way. Such methods can be applied for optimizing designs of such complex systems.
