TÓM TẮT
This paper introduces a procedure to identify maneuvering coefficients bring out abnormal motions in the maneuvering simulation of a submerged body. The first step in responding to abnormal motions in the simulation is the stability analysis. Through the stability analysis, it is confirmed whether the submerged body can be simulated. If it is feasible, secondly, sensitivity analysis is performed to determine the candidate maneuvering coefficients that cause the abnormal motion in the simulation. Finally, we analyze the order of maneuvering coefficients identified through sensitivity analysis and compare it with empirical formulas or other results obtained from model tests. In this study, the dynamics model targeting a high speed submerged body is indirectly verified through the above procedure.
