中文摘要 | 本研究應用現代造船工程所用的計算方法與工具,來比較鄭和寶船復原模型與典型沙船及福船的阻力與速度的關係及穩度安全性。這三種船型的靜水性能及阻力與速度的關係係由一現代船舶設計輔助軟體計算與預估。穩度方面由電腦程式模擬船受風浪時的非線性橫搖運動方程式,以產生相平面來比較其安全性。結果發現鄭和寶船復原模型的穩定與速度性能均遜於福船,但優於沙船。其原因與船型有密切關係,也印證古書中對福船與沙船的比較。同時,我們也發現許多現代船舶的經驗公式並不適用於中國古帆船上。 |
英文摘要 | Modern naval architecture’s tools were used to compare the stability and safety in roll motion and resistance relationship with speed of typical Fu-Chuan, Sha-Chuan, and the replica model of Zheng-He’s treasure ship. These three types of ships’ hydrostatic performance were calculated first. Then, the relationship between power/resistance and velocity was also predicted by modern ship design software. Stability was studied by simulating nonlinear roll motion equation of ships under wind and wave’s action using our own computer program. Phase plane of roll motion was generated to compare the safety among three types. The result shows that the replica model of Zheng-He’s treasure ship is worse than Fu-Chuan, but better than Sha-Chuan in both resistance and stability performance. The reason is highly related with the ship type. This verifies the comparison of Fu-Chuan and Sha-Chuan in ancient Chinese books. We also found that many empirical formulas for modern ship design cannot be applied to ancient Chinese junks. |
