摘要

商用型水陸兩用船其安全性考量以橫搖穩度(rolling stability)為主。本論文嘗試發展一套安裝於水陸兩用船兩舷側內之抗側翻氣囊系統(Anti-Rollover Pneumatic Buoy System, ARPBS)之雛型，當系統偵測到船體橫搖過大時才觸發氣囊之充氣以增加船體之浮力與扶正力矩。我們使用Maxsurf軟體計算水陸兩用船之靜穩度，並據此初步推估氣囊(充滿氣後)的可能尺寸大小，之後進行物理建模與製作水中穩度感測與控制系統，以供初步測試之用。而在空氣中之初步測試的最佳結果為較小氣囊以液態CO2鋼瓶充氣可在6秒內完成。

The major safety concern for commercial amphibious vehicles is how to maintain their stability of rolling. This paper attempts to develop a prototype of the Anti-Rollover Pneumatic Buoy System (ARPBS) installed at both sides of the amphibious vehicle. This system is designed to be capable of detecting excessive rolling motions of the vehicle and then triggering the gas filling of the buoys in order to increase the buoyancy force and the righting moment for the vehicle. We use Maxsurf to calculate the static stability of the vehicle with which the possible sizes of the buoy (after filling up) can be estimated. After that, physical models of the ARPBS including the stability sensing and con-trolling system are constructed for the preliminary testing. The best result of the tests conducted in the air is that the smaller buoy is expanded to the fullest in 6 seconds with the filling of liquefied CO_2.
