摘　　要：以三体船水动力型和K、T响应型(线性和弱非线性)操纵性运动方程为理论基础,以三体船重心运动轨迹微分方程组为数值仿真基础,采用仿真计算工具Matlab软件,对三体船回转运动轨迹、操纵性曲线以及Z型操纵试验曲线等操纵运动特性诸元进行了仿真计算。通过和单体船的对比分析,所得出的计算结果比较合理,计算结果显示三体船较单体船定常回转特性有所下降,而直线稳定性有所加强,跟从性和转首性有所提高。Based on the theory of maneuverability differential equation of hydrodynamic form and K,T responsibility form（both linear and low degree nonlinear equation）, the article took the track motion differential equation of trimaran gravity center as numerical simulation foundation, the maneuverability feature of trimaran including turning tracks, maneuverability curves and zigzag maneuverability curves were calculated by means of Matlab simulation software, the calculation results were compared with that of monohull. The caculated results are reasonable and show that the characteristics of constant turning of the trimaran is less than that of monohull, and beeline stability respectively enhanced, follow-up steering and course changing quality improved.
