【摘要】：隨著現(xiàn)代工業(yè)的發(fā)展,機(jī)械設(shè)備對(duì)液壓技術(shù)的應(yīng)用越來越廣泛,而且正在向高溫、高壓、高速、高效率和高可靠性方向發(fā)展。機(jī)械設(shè)備能否滿足這些要求,往復(fù)密封具有重要的影響作用。然而,長期以來,人們無法從理論上精確計(jì)算出液壓往復(fù)密封的性能參數(shù),而生產(chǎn)中也很難全面合理的對(duì)產(chǎn)品質(zhì)量進(jìn)行評(píng)估,只能從使用過程中得到一些極為有限的確定性較差的間接結(jié)果。因此在傳統(tǒng)的密封設(shè)計(jì)中,大多數(shù)都是憑借經(jīng)驗(yàn)和技巧,設(shè)計(jì)過程帶有很大的試湊性和偶然性,很難在較短時(shí)間內(nèi)設(shè)計(jì)出有效性、可靠性和耐久性都比較高的方案。而即使設(shè)計(jì)出來的密封結(jié)構(gòu),其性能評(píng)價(jià)在實(shí)驗(yàn)之前不可預(yù)見,因此設(shè)計(jì)良好的密封實(shí)驗(yàn)平臺(tái),對(duì)測(cè)試密封圈的性能,改進(jìn)密封圈的密封效果,縮短新產(chǎn)品的研發(fā)周期,提高設(shè)備的密封性能,具有重要意義。本文闡述了密封裝置的實(shí)驗(yàn)原理、實(shí)驗(yàn)?zāi)康暮蛯?shí)驗(yàn)平臺(tái)的功能,對(duì)密封裝置實(shí)驗(yàn)平臺(tái)的方案設(shè)計(jì)進(jìn)行了比較和選擇,并對(duì)密封裝置實(shí)驗(yàn)平臺(tái)的關(guān)鍵技術(shù)進(jìn)行了探索,為了分析實(shí)驗(yàn)結(jié)果,通過有限元分析軟件對(duì)密封件的摩擦力等進(jìn)行了模擬計(jì)算,主要研究內(nèi)容如下：評(píng)述了液壓往復(fù)密封技術(shù)及往復(fù)密封實(shí)驗(yàn)和往復(fù)密封有限元分析技術(shù)的國內(nèi)外研究動(dòng)態(tài),提出液壓往復(fù)密封實(shí)驗(yàn)技術(shù)的發(fā)展趨勢(shì)。通過對(duì)液壓往復(fù)密封技術(shù)的工作過程分析,分析和確定了往復(fù)密封實(shí)驗(yàn)的基本原理和實(shí)驗(yàn)平臺(tái)的功能和目的。根據(jù)密封實(shí)驗(yàn)的基本原理,通過評(píng)估實(shí)驗(yàn)裝置的復(fù)雜性、經(jīng)濟(jì)性和實(shí)驗(yàn)結(jié)果的準(zhǔn)確性等方面設(shè)計(jì)并選擇了有效的往復(fù)密封實(shí)驗(yàn)平臺(tái)方案。并對(duì)液壓往復(fù)密封件的實(shí)驗(yàn)裝置的關(guān)鍵技術(shù),如數(shù)據(jù)采集技術(shù)、控制技術(shù)、結(jié)構(gòu)設(shè)計(jì)等進(jìn)行了深入研究。文中還運(yùn)用ANSYS進(jìn)行了Y形密封圈的分析,得到了密封圈的接觸壓力曲線和間隙咬傷臨界曲線,為密封實(shí)驗(yàn)的數(shù)據(jù)分析提供參考依據(jù)。
[Abstract]:With the development of modern industry, machinery and equipment of hydraulic technology is applied more and more widely, and is the high temperature, high pressure, high speed, high efficiency and high reliability. The development direction of mechanical equipment can meet these requirements, reciprocating seal has an important effect. However, a long time, people can theoretically calculated performance parameters hydraulic reciprocating seal, and the production is also very difficult to comprehensive and reasonable assessment of the quality of products, from in the process of using only some very limited certainty of poor results. So in the indirect sealing design in the traditional, most are based on experience and skills, the design process with a lot of trial and error and accidental and it is difficult to effective design in a relatively short period of time, higher reliability and durability of the scheme. And even if the sealing structure design of the performance evaluation can not be before the experiment See, so the design of good sealing performance test on the experimental platform, the sealing ring, improve the sealing effect of the sealing ring, shorten the development cycle of new products, improve the sealing performance of equipment, which is of great significance. This paper describes the experimental principle of the sealing device, the purpose and the function of the experimental platform, experimental platform of sealing device the scheme of comparison and selection, and the key technology of sealing experiment platform are explored, in order to analyze the experimental results by finite element analysis software to seal friction was simulated. The main research contents are as follows: hydraulic reciprocating reciprocating seal seal technology and finite element analysis technology and the domestic reciprocating seal test research on the dynamic development trend, put forward the experiment of hydraulic reciprocating seal technology. Through the working process of hydraulic reciprocating seal technology analysis, analysis And determine the basic principle and experimental platform of hydraulic reciprocating seal the function and purpose. According to the basic principle of the sealing experiment, by evaluating the complexity of experiment device, economy and experimental results chose effective reciprocating accuracy and other design and seal experimental platform scheme. Key technologies and sealing parts on the hydraulic reciprocating experimental device, such as data acquisition technology, control technology, structure design are discussed. This paper also analyzes the Y ring by ANSYS, the contact pressure curve and the clearance between the sealing ring bite critical curve, provide the reference for the sealing experiment data analysis.
