USING MSC/NASTRAN TO MATCH FREQUENCY RESPONSE TEST DATA

摘要

This paper describes the use of MSC/NASTRAN for matching frequency response test data. MSC/NASTRAN's design optimization capability is used to minimize the difference between the MSC/NASTRAN results and test data. In this procedure, the model parameters are automatically updated until the analytical results match the data. The procedure is built into MSC/NASTRAN via the use of a user-written equation that defines the difference between test and analysis. An example is shown to illustrate the method applied to frequency response test data.
