[0001] The present invention pertains to the field of material and device performance testing, and specifically relates to a multifunctional vacuum friction wear tester capable of simulating the effects of space environment factors (such as a high vacuum environment) and performing friction material and device performance tests. ??Background technique ??[0002] With the development of aerospace and other high technologies, many equipment such as spacecrafts are operated in a high-vacuum environment (10 "Pa ~ 10'Pa" level), and the vacuum environment conditions will bring about special tribological problems. For example, in the absence of oxygen and other atmospheric reactants in the vacuum, the oxide film on the metal surface is quickly removed during the rubbing process, and it is difficult to form a new oxide film. Therefore, the rubbing surface is quickly exposed to the “exposed” state and the fresh metal surface. Severe adhesion occurs in direct contact with each other; there is no diffusion convection of the gas to remove the frictional heat in time, the temperature of the friction surface will rapidly increase, thereby changing the physical properties and chemical stability of the friction material; the liquid lubricant molecules will be in a vacuum. It evaporates at a very high rate, causing rapid loss of lubricant and rendering it ineffective. ??[0003] To solve the problem of lubrication in a vacuum environment and develop various new types of lubricating materials, a large number of tribological experiments must be conducted. Compared with the friction and wear test under the actual working conditions of equipment parts, the laboratory simulation test environment and working conditions are relatively easy to control, the test conditions vary widely, the test cost is relatively low, and the comparative system can be obtained in a short time. data. Therefore, in the research of tribology, the laboratory simulation test has been widely used, and the development of the corresponding test and test equipment and technology is very important. ?[0004] The vacuum friction and wear tester is a basic tool for tribological design and lubrication material selection in a vacuum environment. Because the vacuum friction and wear tester involves key technologies such as vacuum acquisition, dynamic sealing, and real-time signal acquisition, the styling products used for the study of the friction and wear characteristics of materials in a vacuum environment at home and abroad are still scarce. ??[0005] With the increasing attention paid to the problem of vacuum tribology, researchers at home and abroad have carried out the development of a vacuum friction tester. ??[0006] Beijing Institute of Mechanical Industry and Tsinghua University, Cui Zhouping, Liu Jiaxuan and others have developed MT-1 vacuum friction and wear testing machine, the machine can be in a variety of conditions such as vacuum, gas, heating and cooling, friction and wear of materials The mechanism study can provide a pressure environment from the atmosphere to 6.7 X 10 "Pa. Its measurable load and velocity and temperature and vibration characteristics have a wide adjustable range, and the introduction of a computer-aided data acquisition and processing system, measurement parameters Many, repeatability and experimental accuracy are better.Song Baoyu and others of Harbin Institute of Technology also developed the SY-1 vacuum friction and wear tester, which is mainly composed of a friction tester, a vacuum system, and test parameters in a vacuum chamber. It is composed of four parts: the instrument system and the data acquisition and processing system. It can provide a pressure environment of 4 X 10 "Pa, and the speed can be adjusted within the range of 0-2800r/min. It can perform various conditions such as vacuum, charging different gases, heating and cooling. Under the material tribological performance test. The main problem with these devices is that the degree of vacuum that can be provided is too low to realistically simulate the aerospace high vacuum environment in which the spacecraft and others are working. In addition, although the equipment is equipped with a data acquisition system and corresponding software, it was limited by the technical level at the time. The operation and maintenance of the equipment is relatively complicated and the stability needs to be improved. ??[0007] Swiss CSM company produced HVT, VTR two types of vacuum friction and wear testing machine and can provide a 10-Pa high vacuum environment, and pumping high vacuum to 10-5 Pa less than 2 hours, the primary vacuum only It takes 10 minutes. The friction and wear rate during the test can be accurately measured and calculated by the sensor and supporting software. Equipment accuracy and safety ?High, easy to operate. However, the current market price of such equipment is high, the minimum configuration is also more than 200,000 US dollars, and procurement and after-sales service are not very convenient. ??Summary of the Invention ??[0008] The present invention optimizes and integrates an ultra-high vacuum system and a multi-functional friction wear tester, and successfully develops a multi-functional vacuum friction wear tester having an ultimate vacuum of 6×10 Pa. After subsequent expansion, the tester can perform friction and wear tests under vacuum, radiation, corrosion and other special environmental atmospheres, in order to provide more basic equipment for the study of tribology of special conditions. ??[0009] The present invention relates to a multifunctional vacuum friction wear tester, which is mainly composed of a vacuum system, a friction wear system, a power transmission system, and a control system.

[0003] 要解決真空環(huán)境中的潤滑難題，開發(fā)各種新型潤滑材料,必須進(jìn)行大量的摩擦學(xué)實(shí)驗(yàn)。相比于裝備零件實(shí)際工況下的摩擦磨損實(shí)驗(yàn)而言，實(shí)驗(yàn)室模擬試驗(yàn)的環(huán)境和工況因素相對容易控制，試驗(yàn)條件變化范圍寬，試驗(yàn)成本比較低，可在短時(shí)間內(nèi)獲得比較系統(tǒng)的數(shù)據(jù)。因此，在摩擦學(xué)研究中，實(shí)驗(yàn)室模擬試驗(yàn)得到了廣泛的應(yīng)用,相應(yīng)的試驗(yàn)測試設(shè)備和技術(shù)的開發(fā)顯得非常重要。 [0004] 真空摩擦磨損試驗(yàn)機(jī)是進(jìn)行真空環(huán)境工況中摩擦學(xué)設(shè)計(jì)及潤滑材料選擇的基本工具。由于真空摩擦磨損試驗(yàn)機(jī)涉及到真空獲得、動(dòng)密封、實(shí)時(shí)信號采集等難度較大的關(guān)鍵技術(shù)，目前國內(nèi)外用于真空環(huán)境下材料的摩擦磨損特性研究的定型產(chǎn)品還非常匱乏。 [0005] 隨著真空摩擦學(xué)問題越來越受到重視，國內(nèi)外相關(guān)單位的研究人員都曾開展過真空摩擦試驗(yàn)機(jī)的研制。 [0006] 北京機(jī)械工業(yè)管理學(xué)院和清華大學(xué)的崔周平、劉家浚等曾研制了MT-1型真空摩擦磨損試驗(yàn)機(jī)，該機(jī)可在真空、充氣、加熱及冷卻等多種條件下進(jìn)行材料摩擦磨損機(jī)理的研究，可以提供從大氣到6.7X 10 "Pa的壓力環(huán)境,其可測載荷和速度及溫度和振動(dòng)特性都有較寬的可調(diào)范圍,并引入了計(jì)算機(jī)輔助數(shù)據(jù)采集處理系統(tǒng),測量參數(shù)多,重復(fù)性和實(shí)驗(yàn)精度較好。哈爾濱工業(yè)大學(xué)的宋寶玉等人也研制了SY-1型真空摩擦磨損試驗(yàn)機(jī),該機(jī)主要由置于真空室內(nèi)的摩擦試驗(yàn)機(jī)、真空系統(tǒng)、試驗(yàn)參數(shù)測量與儀表系統(tǒng)、數(shù)據(jù)采集處理系統(tǒng)四個(gè)部分構(gòu)成，可以提供4X 10 "Pa的壓力環(huán)境,速度在0-2800r/min范圍內(nèi)可調(diào)，可以進(jìn)行真空、充不同氣體、加熱及冷卻等多種條件下的材料摩擦學(xué)性能測試。這些設(shè)備的主要問題是所能提供的真空度太低，不能真實(shí)模擬航天器等所工作的宇航高真空環(huán)境,此外，設(shè)備雖配備了數(shù)據(jù)采集系統(tǒng)和相應(yīng)的軟件，但因當(dāng)時(shí)技術(shù)水平所限，設(shè)備的操作維護(hù)相對復(fù)雜，穩(wěn)定性也有待提高。 [0007] 瑞士CSM公司生產(chǎn)了HVT、VTR兩個(gè)型號的真空摩擦磨損試驗(yàn)機(jī)并可提供10-帕的高真空環(huán)境，而且抽高真空到10-5帕只需不到2小時(shí)，初級真空只需10分鐘。測試過程中摩擦力和磨損率可通過傳感器及配套軟件自動(dòng)精確測量和計(jì)算。設(shè)備的精度和安全性較 高,操作也較方便。但該類設(shè)備目前的市場價(jià)格較高,最低配置也在20萬美元以上，且采購和售后服務(wù)等都不太方便。 發(fā)明內(nèi)容 [0008] 本發(fā)明將超高真空系統(tǒng)和多功能摩擦磨損試驗(yàn)機(jī)進(jìn)行優(yōu)化集成，成功研制出極限真空度達(dá)到6X 10Pa的多功能真空摩擦磨損試驗(yàn)機(jī)。該試驗(yàn)機(jī)經(jīng)后續(xù)擴(kuò)充后即可進(jìn)行真空、輻射、腐蝕等多種特殊環(huán)境氣氛下的摩擦磨損試驗(yàn)，以期為模擬特殊工況的摩擦學(xué)研究提供更多的基礎(chǔ)設(shè)備。 [0009] 本發(fā)明涉及一~種多功能真空摩擦磨損試驗(yàn)機(jī)，其主要由真空系統(tǒng)、摩擦磨損系統(tǒng)、動(dòng)力傳動(dòng)系統(tǒng)、控制系統(tǒng)構(gòu)成。其中真空系統(tǒng)包括:真空室(1),在真空室(1)的側(cè)壁布置的至少一個(gè)觀察窗(4),用于連接真空泵的真空泵接口法蘭(11),以及在頂蓋上布置的用于配置功能部件的多個(gè)法蘭;摩擦磨損系統(tǒng)包括:用于固定上試樣件卡具(20)的并可在水平和豎直兩個(gè)方向自由旋轉(zhuǎn)的杠桿結(jié)構(gòu)(22),用于固定下試樣盤(6)的試樣平臺(7),其中上試樣摩擦球或摩擦銷(5) 固定在上試樣卡具(20)上,以及設(shè)置在上試樣卡具(20)上的溫度傳感器(2)和壓力傳感器(3) ;動(dòng)力傳動(dòng)系統(tǒng)包括:伺服電機(jī)(9)，伺服電機(jī)(9)通過磁流體聯(lián)軸器(10) 和旋轉(zhuǎn)軸(8) 帶動(dòng)所述試樣平臺(7)和下試樣盤(6)轉(zhuǎn)動(dòng);控制系統(tǒng)包括:用于測量真空室(1)內(nèi)的真空度的復(fù)合真空計(jì),以及用于控制分子泵、機(jī)械泵、高真空電磁擋板閥、摩擦試樣平臺(7)旋轉(zhuǎn)和杠桿結(jié)構(gòu)(22)的電動(dòng)升降機(jī)等功能性部件的控制系統(tǒng)。[0010] 所述試樣卡具(20)具有- -中空部，所述溫度傳感器(2)通過中空部插入上試樣銷或球(5)以
