本研究透過平面運動機構(Planar Motion Mechanism)實驗獲得船舶操縱性導數，並將導數代入運動方程式中，觀察船舶運動的模擬結果，藉此探討船舶在吃水與航行姿態改變時，對其操縱性能的影響，進而得到操縱性能最佳的航行姿態，提供操船者有效率與安全的選擇。
本研究採用貨櫃輪與油輪各一艘的船型進行分析比較，每艘船又分別以兩種排水量(設計吃水、淺吃水)情況分析，而每種排水量各有三種俯仰船況(艉俯[Trim by Bow]、平浮[Evenkeel]、艏俯[Trim by Bow])，分別在本系的拖航水槽進行PMM船模實驗求得操縱性導數，將導數無因次化後代入MMG(Maneuvering Model Group)運動方程式，由電腦程式進行迴旋圈試驗(Turning Circle Test)與Z型試驗(Zig-zag Test)的運動模擬，並比較不同航行情況之模擬結果。
根據本文之研究結果比較，不論在迴旋圈試驗或是Z型試驗，貨櫃輪於設計吃水船況時，平浮為較有利於操縱的航行姿態，淺吃水船況時，艉俯為有利於操縱的航行姿態。油輪則不論於設計吃水或淺吃水時，艏俯為有利於迴旋運動性能的航行姿態，艏俯則為有利於Z型運動的航行姿態。

The main purpose of the present study is to obtain the maneuvering derivatives of different ship sailing attitudes by PMM experiments and find out which is the best ship sailing attitude of steering performance based on the computer program.
There were two types of ships used in the study, including Container and Oil Tanker. The ship test conditions include two different draught for each ship and three sailing attitudes for each draught respectively. Different derivatives can be obtained by different types of PMM experiments for two model ships in the towing tank. After that, these derivatives were applied to the computer program which is based on MMG model to simulate the motion of ship to simulate the turning circle test and the zig-zag test. Finally, the results of the simulations are analyzed in detail to compare the differences between different ship sailing attitudes for two model ships.
From these experiments and analysis, the study can judge the steering performance of the different types of ships and ship sailing conditions. Moreover, the best sailing attitude for maneuvering can be found out.
