In this paper , from the angle of seismic resistance , the parametric sensitivity of the fluid viscous dampers to be used for the bridge is studied in details , and relevant proposals for the dampers are made as well 從抗震角度對(duì)舟山大陸連島工程西堠門(mén)大橋主橋的液體粘滯阻尼器參數(shù)敏感性進(jìn)行了詳細(xì)的研究,并提出建議。
In this thesis , based on the available research of this field , the method to resolve the constraint conditions of the optimization problems has been improved and the parametric sensitivity analysis of the trajectory optimization has been completed . guided by object - oriented method and considering the mission needs and user requirements adequately , the hierarchical structure of the system is analyzed . the uml ( unified modeling language ) is also applied to establish the simulation systems framework 本文在已有研究的基礎(chǔ)上,對(duì)優(yōu)化問(wèn)題的約束處理方法進(jìn)行了改進(jìn),并完成了軌跡優(yōu)化問(wèn)題的靈敏度分析,在面向?qū)ο蠓椒▽W(xué)的指導(dǎo)下,根據(jù)系統(tǒng)的優(yōu)化模型和優(yōu)化策略,分析了系統(tǒng)的層次結(jié)構(gòu),并基于uml建立了仿真系統(tǒng)框架,運(yùn)用泛型技術(shù)進(jìn)行程序設(shè)計(jì),最終實(shí)現(xiàn)了運(yùn)載火箭性能優(yōu)化軟件。
Secondly , according to the requirement of the parametric sensitivity analysis , the method based on orthogonal experiment is chosen to cope with the difficulty of obtaining the sensitivity analysis through the partial derivative of explicit function . and it also overcomes the traditional single factor cyclical method ' s shortcoming ? impossibility to analysis interactional factors . furthermore , some significative conclusions are acquired from the sensitivity analysis 其次根據(jù)軌跡優(yōu)化問(wèn)題靈敏度分析的需要,選取基于正交試驗(yàn)的靈敏度分析方法,解決了軌跡優(yōu)化問(wèn)題沒(méi)有顯函數(shù),無(wú)法通過(guò)求其偏導(dǎo)數(shù)獲得靈敏度的難點(diǎn),同時(shí)克服了傳統(tǒng)的單因素輪換法對(duì)該類(lèi)問(wèn)題進(jìn)行靈敏度分析帶來(lái)的弊端? ?無(wú)法對(duì)有相互作用的因素進(jìn)行靈敏度分析,并通過(guò)對(duì)軌跡優(yōu)化問(wèn)題進(jìn)行靈敏度分析,得出了一些有益的結(jié)論。
