- 中文摘要: 本研究之目的為設計一無線操縱船模之實驗裝置,以量取船模之耐海性能有關數據。 在此研究中發展出一套能在耐海試驗水槽作船模實驗之技巧。此操縱部份包括以無線來控制推進,操舵及數據截取。所有之訊號由感應器接受並由類比信號器轉換成數字貯存於船上之主記憶體。假使耐海試驗水槽夠大的話,本技巧無波向之限制。在本報告中考慮了幾個不同之波向及船速。試驗之結果與截片理論相比較,結果發現,本裝置對於起伏及縱搖運動之量測數據與理論相當吻合。大致上此實驗技巧之設計可證明是成功且有用的,對於船隻之耐海性能研究將有所助益。
- 英文摘要: The purpose of the present research is to design an experimental set-up of a remote-controlled shipmodel for measuring the data of the seakeeping characteristics. In the research, the model test technique in the seakeeping tank using a free-running model is devel-oped. The actions including propelling, steering and data sampling are guided by remote-control. All thesignals are received by sensors and transferred by an A/D system and stored in the Main CPU on board. There is no limitation of the wave headings if the seakeeping tank is large enough. Several waveheadings and ship speeds are handled. The sampling data are compared with the results of strip theory,and we find that the agreements are generally good for heave and pitch motion and the present experi-mental technique is proved to be valid and successful. The results will be helpful for seakeeping researchfor ships.
