摘要
为分析变舵速对船舶Z型运动性能的影响,提出一种理论仿真和模型试验相结合分析的方法。基于流体力学和船舶操纵性基本理论和方法,建立三自由船舶运动模型,并对模型进行仿真验证。通过构建自航模试验系统,进行变舵速下的自航模试验。理论与试验结果表明:不同舵速对K及T指数无明显影响,但对超越角影响较明显。
To analyze the ship Zig-zag motion effects under different rudder speed,a method combine theory with experiment was developed. Based on fluid mechanics and manoeuvrability theory,3- DOF ship motion equation was established,and then the simulation approach was validated for motion equation. The free running model experiments were proceed by construct experiment system. Numerical and experiment results indicate that there is non-obviously effects to K,T indices under different rudder speed. But the overswing angle decreases with the rise of rudder speed.
