Examples of dynamic response optimization using MSC/NASTRAN

The application of MSCINASTRAN, a large scale commercial code, to the optimal design of structures undergoing dynamic excitation is demonstrated using four simple examples. Both frequency and time dependent responses are demonstrated. The disjoint nature of the design space for the example cases is discussed. That is, a given design task can exhibit local minima that a separated from one another by portions of the design spare where the designs are infeasible. Concluding remarks discuss how the nlethodology demonstrated in the siniple examples of this paper can be extended using the generality and flexibility of a large structural analysis system. In addition, some comments are made on further work that could be done to extend the application antl functionality of dynamic response optimization.
