【摘要】：隨著國防現(xiàn)代化的推進(jìn),對(duì)某些國防設(shè)備關(guān)鍵機(jī)構(gòu)同時(shí)提出了輕量化和高性能設(shè)計(jì)要求,因此產(chǎn)品的可靠性問題日益重要。XX機(jī)構(gòu)考慮可靠性的多學(xué)科優(yōu)化的分析研究就是在此背景下提出來的。 機(jī)構(gòu)的多學(xué)科優(yōu)化設(shè)計(jì)研究在西方發(fā)達(dá)國家已經(jīng)成熟地應(yīng)用于航空、航天、武器裝備、汽車以及電子通信等高科技行業(yè)。對(duì)于我國來說在此領(lǐng)域的研究還處于開始階段,與發(fā)達(dá)國家的技術(shù)差距還很大。 本文研究的主要是針對(duì)XX機(jī)構(gòu)可靠性的多學(xué)科優(yōu)化設(shè)計(jì)進(jìn)行分析,主要內(nèi)容如下: 首先介紹了可靠性以及多學(xué)科優(yōu)化領(lǐng)域在國內(nèi)外的發(fā)展現(xiàn)狀以及相關(guān)的理論知識(shí)體系,然后將整個(gè)論文的框架結(jié)構(gòu)以及內(nèi)容作了簡單的闡述。其次是對(duì)XX機(jī)構(gòu)的仿真建模階段研究。主要采取了試驗(yàn)設(shè)計(jì)分析,然后實(shí)現(xiàn)機(jī)構(gòu)三維實(shí)體建模,最后對(duì)機(jī)構(gòu)進(jìn)行動(dòng)力學(xué)仿真分析。試驗(yàn)設(shè)計(jì)方案采用正交試驗(yàn)法,其選取的數(shù)據(jù)點(diǎn)具有很強(qiáng)的代表性以及高效性。 然后是基于仿真實(shí)驗(yàn)數(shù)據(jù)進(jìn)行響應(yīng)面的擬合,得到相關(guān)的函數(shù)表達(dá)式,以便于后期多學(xué)科優(yōu)化的工作的展開。 最后是多學(xué)科優(yōu)化的分析研究。根據(jù)實(shí)際調(diào)研以及經(jīng)驗(yàn),我們將該機(jī)構(gòu)的設(shè)計(jì)劃分為三個(gè)學(xué)科:性能學(xué)科、重量學(xué)科以及可靠性學(xué)科,來選取最優(yōu)解,以滿足工程上的設(shè)計(jì)需要。
[Abstract]:With the development of national defense modernization, some key institutions of national defense equipment have put forward the requirement of lightweight and high performance design at the same time. Therefore, the problem of product reliability is becoming more and more important. The research on multidisciplinary optimization design of institutions has been applied to the high-tech industries such as aviation, aerospace, weapons and equipment, automobile and electronic communication in the western developed countries. For our country, the research in this field is still at the beginning stage, and the technological gap with developed countries is still very big. In this paper, the reliability of XX mechanism of multidisciplinary optimization design analysis, the main content is as follows: This paper first introduces the development of reliability and multidisciplinary optimization at home and abroad as well as the relevant theoretical knowledge system, and then gives a brief description of the framework and content of the whole paper. Secondly, the research on the simulation modeling stage of XX mechanism. The experiment design and analysis are adopted, and the 3D solid modeling of the mechanism is realized. Finally, the dynamics simulation analysis of the mechanism is carried out. The orthogonal test method is used in the design of the test, and the selected data points are highly representative and efficient. Then the response surface is fitted based on the simulation experimental data, and the related functional expressions are obtained to facilitate the work of multidisciplinary optimization in the later stage. Finally, the analysis and research of multi-disciplinary optimization. According to the actual investigation and experience, we divide the design of the mechanism into three disciplines: performance, weight and reliability to select the optimal solution to meet the needs of engineering design.
