《動(dòng)態(tài)系統(tǒng)可靠性分析--高效方法及航空航天 應(yīng)用(英文版)(精)/大飛機(jī)出版工程》編著者吳 斌。
《動(dòng)態(tài)系統(tǒng)可靠性分析--高效方法及航空航天 應(yīng)用(英文版)(精)/大飛機(jī)出版工程》針對(duì)動(dòng)態(tài) 系統(tǒng)的可靠性分析,闡述了一種新的優(yōu)化技術(shù),即針 對(duì)低頻率諧 振動(dòng)力載荷下的工程產(chǎn)品結(jié)構(gòu)可靠性問題,使用綜合 的快速概率方法,也即“擾動(dòng) 算法+蒙特卡洛方法”。在針對(duì)兩個(gè)航空航天實(shí)際工 程案例的應(yīng)用中發(fā)現(xiàn),運(yùn)用此 方法能快速準(zhǔn)確地解決失效面高非線性、大量計(jì)算強(qiáng) 度和動(dòng)態(tài)系統(tǒng)高復(fù)雜度等原 有概率方法的應(yīng)用困難。本書的出版填補(bǔ)了國(guó)際上對(duì) 高效快速概率方法的研究空 白。
本書可供從事民用飛機(jī)結(jié)構(gòu)可靠性安全性工程設(shè) 計(jì)分析、試驗(yàn)、管理的技術(shù)人 員和相關(guān)專業(yè)的研究生使用。
《動(dòng)態(tài)系統(tǒng)可靠性分析--高效方法及航空航天應(yīng)用(英文版)(精)/大飛機(jī)出版工程》編著者吳斌。 本書根據(jù)作者在劍橋大學(xué)工程系可靠性專業(yè)多年研究成果和近幾年來在中國(guó)商飛公司民機(jī)研制的實(shí)踐經(jīng)驗(yàn)編撰而成,主要闡述了一種處理工程結(jié)構(gòu)可靠性和安全性問題的綜合優(yōu)化方法,即針對(duì)低頻率諧振動(dòng)力載荷下的復(fù)雜的工程產(chǎn)品結(jié)構(gòu)可靠性問題,使用綜合的快速概率方法。此方法旨在克服概率方法應(yīng)用的困難,比如失效面的高非線性問題、大量的計(jì)算強(qiáng)度和動(dòng)態(tài)系統(tǒng)的高復(fù)雜度等。這是在總結(jié)現(xiàn)有的各種分析方法的基礎(chǔ)上,提出的一種最新的基于非確定因素的概率分析方法,體現(xiàn)國(guó)際最新發(fā)展。
