摘要

A frequency domain-based analysis of a submarine maneuvering model has been completed and used to study the effects of parameter uncertainty. The maneuvering model of the BB1-X submarine has been analyzed for the purpose of understanding the consequences of reduced input fidelity. Inputs were varied individually and ranked based on the resulting deviation from the original model. The model was also reduced to include fewer degrees of freedom or dynamic effects and compared with the original fully detailed model. The intention of this study is to determine which data are most crucial to the accurate maneuvering simulation of a submarine. Depending on the application of such a model, certain accuracies may be sacrificed to reduce resource requirements and save cost. The results of this study give some guidance as to which types of parametric data need to be the most detailed. Although the results will not give exact sensitivities for all submarine maneuvering models, it will give an indication of which areas should be focused on.
