摘　　要：舰船领域的研究中,运动特性分析是重点内容,在研究过程中,可以采用非线性数学模型。通过对舰船运动特性的准确分析,能够为运动预报提供可靠依据,从而确保舰船上武器系统的发射精度。不仅如此,舰船的运动预报准确度与舰载飞机起落降的安全性有着密切关联,还能为舰船耐波性的研究提供帮助。在对舰船运动模型进行构建的过程中,可以选用MMG分离模型。基于此,以分离模型作为主要依据,对相关的数学模型进行构建,分析船舶在海面上的运动特性。In the research in the field of ships,the analysis of motion characteristics is the key content.In the research process,nonlinear mathematical models can be used.Through accurate analysis of the ship’s motion characteristics,it can provide a reliable basis for motion prediction,thereby ensuring the launch accuracy of the ship’s weapon system.Not only that,the accuracy of ship motion prediction is closely related to the safety of carrier-based aircraft taking off and landing,and it can also provide help for the research on ship seakeeping.In the process of constructing the ship motion model,the MMG separation model can be selected.Based on this,the separation model is used as the main basis to construct related mathematical models to analyze the movement characteristics of ships on the sea.
