【摘要】：測量型自主水下航行器(AUV)垂直面運(yùn)動(dòng)穩(wěn)定性對(duì)于其順利完成長時(shí)間深海作業(yè)、保證航行效率和安全性至關(guān)重要。以天津大學(xué)研制的用于海底地形地貌測量的深水AUV為應(yīng)用對(duì)象,根據(jù)古爾維茨判別法推導(dǎo)了其垂直面運(yùn)動(dòng)穩(wěn)定性衡準(zhǔn)表達(dá)式,通過數(shù)值模擬水池試驗(yàn)獲得了穩(wěn)定性衡準(zhǔn)判別式所需的水動(dòng)力導(dǎo)數(shù),分析了不同水動(dòng)力外形因素(主體外形和尾翼布局形式)對(duì)其運(yùn)動(dòng)穩(wěn)定性的影響。結(jié)果表明,具有較大縱中剖面投影面積的水動(dòng)力外形的AUV,以及擁有X尾翼布局的AUV具有更好的垂直面運(yùn)動(dòng)穩(wěn)定性。
[Abstract]:The stability of the vertical plane motion of the measured autonomous underwater vehicle (AUV) (AUV) is very important for the successful completion of the long time deep sea operation and the guarantee of navigation efficiency and safety. Taking the Deepwater AUV developed by Tianjin University for submarine topographic survey as an application object, according to Guerwitz's discriminant method, the accurate expression of motion stability of vertical plane is derived. The hydrodynamic derivatives needed for the stability criterion are obtained by numerical simulation of the pool test. The influence of different hydrodynamic shape factors (the main body shape and the tail configuration form) on the motion stability is analyzed. The results show that AUV, with large projection area of longitudinal profile and AUV with X tail have better stability of vertical plane motion.
