摘要

针对浅海浮标系泊结构姿态控制问题,进行系统参数优化匹配计算方法研究.首先进行系泊结构力学分析,建立系统的力和力矩平衡方程,推导出系泊系统状态的描述方程;采用系泊系统起锚角和检测设备舱的倾斜角度为约束条件,取锚链型号和重物球质量作为设计变量,建立锚链的垂直高度相对误差最小为目标的系统参数优化匹配的数学模型;用最小二乘法求解非线性方程组,进行分层变量优化计算.所提出的系泊系统结构参数优化计算方法可为浮标系泊系统结构设计提供理论依据.%In order to solve the problem of attitude control of shallow sea buoy mooring system, the method of system parameter matching calculation is studied. First carry on the analysis of mooring structure mechanics, and establish the sys-tem of the force and moment equilibrium equations describing equations of mooring system state; the anchor angle of the mooring system and the tilt angle of detection equipment cabin as constraint conditions, take the quality of anchor type and heavy ball as the design variables, parameters optimization mathematical model, establish the system of vertical height the relative error of the target chain; using the least square method for solving nonlinear equations, stratified variable optimiza-tion. The proposed method can provide theoretical basis for the design of buoy mooring system.
