【摘要】：隨著國防現(xiàn)代化的推進,對某些國防設備關(guān)鍵機構(gòu)同時提出了輕量化和高性能設計要求,因此產(chǎn)品的可靠性問題日益重要。XX機構(gòu)考慮可靠性的多學科優(yōu)化的分析研究就是在此背景下提出來的。 機構(gòu)的多學科優(yōu)化設計研究在西方發(fā)達國家已經(jīng)成熟地應用于航空、航天、武器裝備、汽車以及電子通信等高科技行業(yè)。對于我國來說在此領域的研究還處于開始階段,與發(fā)達國家的技術(shù)差距還很大。 本文研究的主要是針對XX機構(gòu)可靠性的多學科優(yōu)化設計進行分析,主要內(nèi)容如下: 首先介紹了可靠性以及多學科優(yōu)化領域在國內(nèi)外的發(fā)展現(xiàn)狀以及相關(guān)的理論知識體系,然后將整個論文的框架結(jié)構(gòu)以及內(nèi)容作了簡單的闡述。其次是對XX機構(gòu)的仿真建模階段研究。主要采取了試驗設計分析,然后實現(xiàn)機構(gòu)三維實體建模,最后對機構(gòu)進行動力學仿真分析。試驗設計方案采用正交試驗法,其選取的數(shù)據(jù)點具有很強的代表性以及高效性。 然后是基于仿真實驗數(shù)據(jù)進行響應面的擬合,得到相關(guān)的函數(shù)表達式,以便于后期多學科優(yōu)化的工作的展開。 最后是多學科優(yōu)化的分析研究。根據(jù)實際調(diào)研以及經(jīng)驗,我們將該機構(gòu)的設計劃分為三個學科:性能學科、重量學科以及可靠性學科,來選取最優(yōu)解,以滿足工程上的設計需要。
[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.
