【摘要】：隨著科技的進(jìn)步和人類文明的發(fā)展,慣性技術(shù)已經(jīng)被廣泛地應(yīng)用于武器裝備、民用器械等方面。作為這一技術(shù)承載體的慣性導(dǎo)航系統(tǒng)設(shè)備則是主要的代表產(chǎn)品之一,其特點(diǎn)是可靠性高,能在復(fù)雜的環(huán)境中進(jìn)行正常的工作,且壽命長,可以不借助外界信號進(jìn)行自主導(dǎo)航定位。目前對于這一代慣性導(dǎo)航系統(tǒng)設(shè)備的壽命預(yù)測并沒有權(quán)威的答案。本文的目的正在于用適當(dāng)?shù)姆椒▽δ承吞枒T性導(dǎo)航系統(tǒng)設(shè)備進(jìn)行壽命預(yù)測,給出一個合理的壽命值。但是,受限于慣性導(dǎo)航系統(tǒng)設(shè)備的高成本和核心部件的保密性,以及測試時間不能太長符等客觀現(xiàn)實(shí),傳統(tǒng)壽命試驗(yàn)無法對其進(jìn)行壽命評估。而此時加速壽命試驗(yàn)則非常適用。加速壽命試驗(yàn)通過提高產(chǎn)品工作環(huán)境的應(yīng)力水平,從而達(dá)到加速產(chǎn)品失效,縮短試驗(yàn)時間,提高試驗(yàn)效率之目的。本文圍繞慣性導(dǎo)航系統(tǒng)設(shè)備的加速壽命試驗(yàn)及其壽命預(yù)測方法等問題開展研究,其主要內(nèi)容如下:(1)對慣性導(dǎo)航系統(tǒng)設(shè)備的結(jié)構(gòu)、工作原理、失效模式及失效機(jī)理等進(jìn)行研究,結(jié)合試驗(yàn)和經(jīng)驗(yàn)數(shù)據(jù),找出慣性導(dǎo)航系統(tǒng)設(shè)備中存在的薄弱環(huán)節(jié)。(2)開展慣性導(dǎo)航系統(tǒng)參數(shù)長期穩(wěn)定性誤差模型分析,確立多套待試驗(yàn)慣性導(dǎo)航系統(tǒng),部分慣性導(dǎo)航系統(tǒng)進(jìn)行加速退化試驗(yàn),其他慣性導(dǎo)航系統(tǒng)則自然老化,完成了數(shù)據(jù)的收集。(3)確定了慣性導(dǎo)航系統(tǒng)設(shè)備的加速壽命試驗(yàn)類型、試驗(yàn)應(yīng)力水平和試驗(yàn)方案,完成了試驗(yàn)并進(jìn)行了加速壽命試驗(yàn)數(shù)據(jù)分析,運(yùn)用合理的計算方法計算出了某型號慣性導(dǎo)航系統(tǒng)設(shè)備的壽命值。本文的研究成果為慣性導(dǎo)航系統(tǒng)的壽命評估,和新一代裝備平臺的研制提供參考。
[Abstract]:With the progress of science and technology and the development of human civilization, inertial technology has been widely used in weapons, civil equipment and so on. The inertial navigation system equipment, which is the carrier of this technology, is one of the main representative products. It is characterized by its high reliability, its ability to perform normal work in complex environments, and its long life span. Autonomous navigation and positioning can be carried out without the help of external signals. There is no definitive answer to life prediction for this generation of inertial navigation system equipment. The purpose of this paper is to predict the life of a certain type of inertial navigation system and give a reasonable life value. However, limited by the high cost of inertial navigation system equipment and the confidentiality of the core components, and the test time can not be too long, the traditional life test can not evaluate its life. The accelerated life test is very suitable. The accelerated life test can accelerate the failure of the product, shorten the test time and improve the test efficiency by raising the stress level in the working environment. In this paper, the accelerated life test and life prediction methods of inertial navigation system equipment are studied. The main contents are as follows: 1) the structure, working principle, failure mode and failure mechanism of inertial navigation system equipment are studied. Combined with test and experience data, find out the weak link in the equipment of inertial navigation system. (2) analyze the error model of inertial navigation system parameter long-term stability, and establish many sets of inertial navigation system to be tested. Some inertial navigation systems perform accelerated degradation tests, while other inertial navigation systems naturally age. The data collection is completed. The accelerated life test types, test stress levels and test schemes of inertial navigation system equipment are determined. The test was completed and the data of accelerated life test were analyzed. The life of a certain type of inertial navigation system equipment was calculated by using reasonable calculation method. The research results in this paper provide a reference for the life evaluation of inertial navigation system and the development of new generation equipment platform.
