摘要
本文对船舶航行过程进行分析,着重研究船舶在航行过程中的流场理论,并对船舶受到的阻力进行分析,同时给出船舶摩擦阻力和傅汝德数之间的关系;基于计算流体力学对船舶航行过程中的受力情况进行仿真分析,探讨波浪流速对船舶航行过程的影响,同时对波浪抨击下的船体受力情况进行分析。最后,构建出船舶压力监测系统。本文对船体行驶过程中压力监测方法的研究,有助于推动船舶结构安全技术的发展。
The ship navigation process is analyzed,and the flow field theory of the ship in the navigation process is emphatically studied.The resistance of the ship is analyzed,and the relationship between the ship friction resistance and the Froude number is given.Based on computational fluid dynamics,the force situation of the ship during navigation is simulated and analyzed,and the influence of wave velocity on the ship's navigation process is discussed.At the same time,the force situation of the ship under wave attack is analyzed.Finally,the ship pressure monitoring system is constructed.The research on pressure monitoring methods in the process of ship hull situation in this paper will contribute to the rapid development of ship structure safety technology.
