摘要

本研究提出了一种在模拟水下物体时识别导致异常运动的机动系数的方法。应对异常运动的第一步是进行稳定性分析,以确定是否可以模拟潜水体。如果这样做是可行的,则进行灵敏度分析,以确定导致模拟中异常运动的机动系数。最后,我们分析了通过灵敏度分析确定的机动系数的阶数。我们还将其与经验公式和模型试验的其他结果进行了比较。通过上述程序间接验证了以高速水下物体为目标的动力学模型。在本研究中,验证了动力学模型的有效性,并根据开发的程序识别了导致异常运动的参数。

A Study on Verification of the Dynamic Modeling for a Submerged Body Based on Numerical Simulation
This study proposed a procedure to identify maneuvering coefficients that brought about abnormal motions in the simulation of a submerged body. The first step in responding to abnormal motions was conducting stability analysis to determine whether the submerged body could be simulated. If doing so was feasible, sensitivity analysis was then performed to determine maneuvering coefficients that caused the abnormal motion in the simulation. Finally, we analyzed the order of maneuvering coefficients identified by the sensitivity analysis. We also compared it with empirical formulas and other results obtained from model tests. The dynamics model targeting a high-speed submerged body was indirectly verified by the above procedure. In this study, the effectiveness of the dynamic model was verified, and parameters causing the abnormal motion were identified in accordance with the developed procedure.
