摘要
Sensitivities of hydrodynamic derivatives in the mathematical model for maneuvering the underwater vehicle NPS II are analyzed with direct method. The mathematical model is simplified based on the total sensitivity values of the hydrodynamic derivatives and the defined selective function. Then maneuvering simulations are carried out with the simplified model and the original model respectively. The comparison of the simulation results demonstrates the validity of the model simplification, which is feasible in analyzing sensitivities of hydrodynamic derivatives. ©, 2015, The Editorial Board of Ship Building of China.
