2、計(jì)的研究也很少。針對(duì)上述的研究現(xiàn)狀并結(jié)合某運(yùn)載AUV的安全分離問(wèn)題,對(duì)操縱性優(yōu)化設(shè)計(jì)及其在AUV分離運(yùn)動(dòng)中的應(yīng)用進(jìn)行了研究,主要研究成果和創(chuàng)新點(diǎn)如下:l、運(yùn)用動(dòng)量定理和動(dòng)量矩定理建立了水下航行器的空間運(yùn)動(dòng)數(shù)學(xué)模型。2、研究了AUV的操縱性響應(yīng)方程和K.T操縱性指數(shù)。并針對(duì)特征根全部為實(shí)根和有復(fù)根的情況,對(duì)操縱性的評(píng)價(jià)指數(shù)和過(guò)渡函數(shù)進(jìn)行了研究,完善了文獻(xiàn)的內(nèi)容。3、對(duì)多目標(biāo)優(yōu)化設(shè)計(jì)的概念、解的定義和遺傳算法的概念,基本原理以及特點(diǎn)進(jìn)行了闡述,對(duì)遺傳算法的改進(jìn)進(jìn)行了研究。。4、分析和研究了傳統(tǒng)的操縱性優(yōu)化設(shè)計(jì)模型的局限性
3、。本文從混合操縱性模型出發(fā),提出了以鰭舵力和鰭舵力作用點(diǎn)距浮心的距離為設(shè)計(jì)變量的操縱性優(yōu)化設(shè)計(jì)新模型(包括單目標(biāo)和多目標(biāo)模型),并對(duì)某AUV進(jìn)行了操縱性優(yōu)化設(shè)計(jì),結(jié)果證明了操縱性優(yōu)化設(shè)計(jì)新模型的有效性。并表明了穩(wěn)定性和機(jī)動(dòng)性相互制約的關(guān)系。關(guān)鍵詞:自主水下航行器操縱性操縱性指數(shù)K,T分析操縱性優(yōu)化設(shè)計(jì)模型多目標(biāo)優(yōu)化遺傳算法論文類型:應(yīng)用研究H英文摘要IISubject:ManeuverabilityOptimalDesignofAUVSpeciality:MeasurementTechnologyandInstrum
