摘　　要：为完成水下驻留航行器锚泊机构段的设计工作,首先需要应用锚泊线静力特性分析方法完成锚泊线选型设计。建立了锚泊线稳态运动控制方程,在分析锚泊线弹性模量、密度与阻力系数等参数对稳态锚泊姿态及张力分布影响的基础上选定锚泊线材料。另外,针对水下驻留航行器两种极限锚泊姿态工况,模拟仿真了锚泊线悬链部分长度、锚泊深度以及航行器负浮力之间的关系。综合考虑这2种极限状态合理选取锚泊线长度与航行器负浮力,保证驻留系统安全性,避免发生走锚、触底现象的同时,尽可能减少锚泊机构段空间尺寸。To complete the design of the mooring mechanism segment for lurk unmanned underwater vehicle(UUV),the primary task is to accomplish selection design of mooring line using mooring line's static characteristic analysis method.The steady state motion control equation of mooring line is established,material of mooring line is selected based on analyzing effects of elastic modulus,density,drag coefficient and other parameters of mooring line on steady state mooring attitude and tension distribution.In addition,the relation among length of mooring line's catenary,mooring depth and negative buoyancy of vehicle is simulated under2ultimate mooring attitude conditions.Taking the2ultimate conditions into comprehensive consideration,the length of mooring line and the negative buoyancy of vehicle are selected reasonably to guarantee security of the mooring system,the space dimension of mooring mechanism segment is reduced in the premise of avoiding the case of anchor dragging or grounding.
