  1. 船舶運動及控制 指導教授:曾慶耀 學生:林柏廷 學號:19967001

  2. Index • Introduction • Similitude • Standard Maneuvering Test

  3. Introduction 船體六個自由度: 平移

  4. Introduction 船體六個自由度: 旋轉

  5. Introduction 自由度的探討因載具不同而不盡相同 一般討論為 縱移(surge)、橫移(sway)、以及平擺(yaw)。 Ex:實驗小船 也有四個自由度縱移(surge)、橫移(sway)、平擺(yaw)以及橫搖(roll)。 Ex:貨櫃輪

  6. Introduction 或者探討縱移(surge)、橫移(sway)、俯仰(pitch)、平擺(yaw) 。 Ex:潛水艇

  7. Introduction 速度=>u,v,w 質心=>XG,YG,ZG 角速度=>p,q,r 外力=>X,Y,Z

  8. Introduction

  9. Introduction 舵角=>打舵的角度,打右舵向右迴旋 舵角的限制為正負35度

  10. Introduction 旋轉軸心=>一般於船艏後方1/4或1/5船長的 地方。 定義:旋轉以及橫移的合成效應,而該點僅 有旋轉(pure yaw)而無橫移速度存在。 須滿足 v+X.r=0的關係式。

  15. Standard Maneuvering Test Dieudonne Spiral

  16. Standard Maneuvering Test Zig-Zag Maneuver

  17. Standard Maneuvering Test Drift Angle: 偏航角如同升力面的攻角 來描述船隻旋轉時的滑行

  18. Standard Maneuvering Test Speed Loss: 攻角伴隨的阻力使得速度下降。
